What is the following probability? P(A and B) = Are A and B mutually exclusive? Why or why not?
"

Answers

Answer 1

The values of the probabilities if A and B are mutually exclusive are:

P(A and B) = 0

P(A or B) = 0.9

P(not A) = 0.85

P(not B) = 0.25

P(not (A or B)) = 0.1

P(A and (not B)) = 0.15

Given that the events A and B are mutually exclusive.

So, P(A and B) = 0.

It is also given that, Probability of event A = P(A) = 0.15

and Probability of event B = P(B) = 0.75

From the formula we know that,

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.15 + 0.75 - 0

P(A or B) = 0.9

Now, Probability of Universal Event is always 1.

P(not A) = 1 - P(A) = 1 - 0.15 = 0.85

P(not B) = 1 - P(B) = 1 - 0.75 = 0.25

P(not (A or B)) = 1 - P(A or B) = 1 - 0.9 = 0.1

Since (A and (not B)) event refers to only event A.

So, P(A and (not B)) = P(A) = 0.15

(Beautiful Mind) There is an interesting scene in A Beautiful Mind in which John Nash's character discovers his equilibrium concept. The setup is that there are four men and five women at a bar, and each man must simultaneously walk over to a woman. One of the women, who is blonde, is considered to be more desirable than the other four, who are all brunettes. Although the men all prefer the blonde to the brunettes, if they all go for the blonde they will "block each other" (according to the logic of the movie) and end up unsuccessful; moreover, after going for the blonde, they cannot then go to a brunette because the brunette would be offended at being someone's second choice and would turn down the man. Nash's character then realizes that what ought to happen is for each of the four men to choose a brunette. Let's try to put this situation in a game theoretic model by using a to denote the payoff a man would receive if another man goes for the same woman he does (here there are assumptions that it is possible to "block each other" on brunettes and that being "blocked" on a brunette gives the same payoff as being "blocked" on a blonde, although this is not important for the problem). We'll use b to refer to a man's payoff if he is the only man to go for a woman and that woman is a brunette. We'll use c to refer to a man's payoff if he is the only man to go for a woman and that woman is blonde. The natural restrictions on payoffs are a < b < c. Is there a pure strategy Nash equilibrium where each man ends up with a brunette? What are the pure strategy Nash equilbria? How do these answers change if the blonde turns down everyone (meaning that the payoff to going to the blonde is a, regardless of how many men choose her)? [Hint: classify situations based on how many men go to the blond woman.]

Answers

In the absence of the blonde turning down everyone, the pure strategy Nash equilibrium is for all men to choose brunettes. If the blonde turns down everyone, the pure strategy Nash equilibrium remains the same: all men choosing brunettes.

How to explain the Nash equillbrium

In this case, all four men choose brunettes. Since no man is going for the blonde, their payoff is b if they are the only man going for a brunette. This scenario is a pure strategy Nash equilibrium because no man has an incentive to deviate.

If one man goes for the blonde, his payoff is c. The other three men choose brunettes, resulting in a payoff of b. This situation is not a Nash equilibrium because the man going for the blonde has an incentive to deviate and choose a brunette instead, increasing his payoff to b.

Since the payoffs are the same for any number of men going for the blonde, the pure strategy Nash equilibrium is for all men to choose brunettes. Each man's payoff will be b, regardless of whether they choose the blonde or a brunette.

Can someone plz explain how to do this

Answers

Answer:

-2

Step-by-step explanation:

First, you need to find the equation.

f(x) = -3x + b

Now we need to find the y-intercept.

f(x) = -3x + b

f(-9) = -3(1) + b

-9 = -3 + b

-6 = b

f(x) = -3x - 6

The zero of f means that f(x) = 0

f(0) = -3x - 6

f(6) = -3x

x = -2

Answers

Answer:

[tex]0.64*y = 40[/tex]

Step-by-step explanation:

Answer:

64/100=40/y

Step-by-step explanation:

We use the simple equation of finding percentages, which would be the percentage (64) over 100 percent, as this is our total. If 64 percent of y equals 40, then the equation is 64/100=40/y. To solve for y, multiply 100 x 40= 4000, then divide by 64 to get the answer. Y=62.5

Answers

Answer:

The actual diameter of Venus is 12,100 kilometers.

Step-by-step explanation:

Since William is building a planetary path for people to walk through, and the planetary path will have a model of the sun and model of the planet, and William uses two different scales, he uses 1 cm to 1000 km for the diameter of each planet and 1m to 1000000km for the distance of the sun to each planet, if William makes a model of planet Venus and the model has a diameter of 12.1, to work out the real diameter of Venus the following calculation must be performed:

1 cm = 1000 km

12.1 cm = X km

1 = 1000

12.1 = X

12.1 x 1000/1 = X

12,100 = X

Thus, the actual diameter of Venus is 12,100 kilometers.

Step-by-step explanation:

From the data:

Pets data:

3,3,4,4,4,4,5,5,5,5

Using calculator:

Median value = 4

Mean absolute deviation = 0.64

Range = 5 - 3 = 2

Siblings data:

Median value = 2

Mean absolute deviation = 1.52

Range = 5 - 0 = 5

Median value of pets > median value of siblings data

Range of siblings data > range of pets data

Mean absolute deviation of siblings data >Ean absolute deviation of pets data

Variability of pets data is lesser than that of siblings data ; as shown by the mean absolute deviation value

If one of the effects is substantial, it should be included in the analysis as a control variable.

If none of the effects are important, the analysis may need to be redone with a more comprehensive model or a bigger sample size.

If you conduct a two-way between-subjects ANOVA and discover that the interaction F-test is important, the next thing to do is to interpret the results.

You may be interested in estimating the main effects of each variable and the interaction effect.

In a two-way ANOVA, a statistical method is employed to identify the interactions between two variables.

ANOVA stands for analysis of variance.

It is a statistical method used to compare two or more populations by analyzing the variance between them.

F-test is a statistical method used to compare two variances or to test hypotheses about whether two population variances are equal.

It can be used to compare more than two variances in ANOVA.

When the interaction effect in a two-way between-subjects ANOVA is important, the interpretation of the main effects of each variable and the interaction effect must be done.

In which cases could comparing the observed and expected distributions help detect peculiarities in the data
1. A newly discovered secret novel from a deceased prolific author
2. The reported ages of users on a popular social networking site
3. Both of the above
4. None of the above

Answers

Comparing the observed and expected distributions can help detect peculiarities in the data in cases where there is an expectation or a known pattern that can be used for comparison.

A newly discovered secret novel from a deceased prolific author: In this case, comparing the observed distribution of the writing style, themes, or language in the novel with the expected distribution based on the author's previous works can help identify any peculiarities or deviations from the author's typical style.

The reported ages of users on a popular social networking site: Comparing the observed distribution of ages with the expected distribution based on demographic data or population statistics can reveal any anomalies or discrepancies, such as an unusually high or low frequency of certain age groups, which may indicate data inaccuracies or biases.

Both of the above: Both scenarios involve comparing observed and expected distributions to identify peculiarities or deviations in the data.

None of the above: If there is no expectation or known pattern to compare the observed distribution against, comparing the observed and expected distributions may not be applicable for detecting peculiarities in the data.

In conclusion, comparing observed and expected distributions can be helpful in detecting peculiarities in the data when there is an expectation or known pattern to use for comparison. It can be useful in scenarios such as analyzing a newly discovered novel from a deceased author or examining reported ages on a social networking site. However, if there is no expectation or known pattern, this method may not be applicable.

If f(x) is irreducible over R. then f(x²) is irreducible over R. True / False

Answers

The statement "If f(x) is irreducible over R, then f(x²) is irreducible over R" is false. The irreducibility of f(x) does not guarantee the irreducibility of f(x²) over R.

Does the irreducibility of f(x) over R imply the irreducibility of f(x²) over R? True / False

The statement "If f(x) is irreducible over R, then f(x²) is irreducible over R" is actually false. In other words, just because a polynomial, f(x), is irreducible over the real numbers (R), it does not necessarily mean that its square, f(x²), will also be irreducible over R.

To understand why, let's first clarify the concept of irreducibility.

A polynomial is considered irreducible if it cannot be factored into a product of two or more non-constant polynomials with coefficients in the same field. In this case, we are considering the field of real numbers (R).

Now, when we square a polynomial, such as f(x)² or f(x²), it can lead to changes in its factorization.

The squared polynomial may introduce new factors or change the multiplicity of existing factors.

This means that the irreducibility of the original polynomial, f(x), does not necessarily carry over to the squared polynomial, f(x²).

To illustrate this, let's consider an example. Suppose we have a polynomial f(x) = x² + 1, which is irreducible over R. If we square this polynomial, we get f(x²) = (x² + 1)² = x⁴ + 2x² + 1.

The squared polynomial, in this case, is no longer irreducible over R because it can be factored as (x² + 1)(x² + 1).

This example shows that the irreducibility of f(x) does not imply the irreducibility of f(x²). It's important to carefully analyze the specific factors and properties of each polynomial to determine its irreducibility.
