The probability that all symbols are different is 0.45 and the probability that all all symbols are different and the first number is the largest among the numbers is 0.11.
There are three places for alphabets, which can be filled by any one of the 26 letters. So the total possible ways of selecting 3 letters is 26³.
There are four places for alphabets, which can be filled by any one of the 10 digits. So the total possible ways of selecting 4 numbers is [tex]10^{4}[/tex].
So, the total possible ways of selecting 3 alphabets and 4 numbers for license plates is 26³ × [tex]10^{4}[/tex] = 175760000.
(a) The probability that all symbols are different.
The three letters can be selected in 26! ways = 26 × 25 × 24 = 15600
Similarly, the four numbers can be selected in 10! ways = 10 × 9 × 8 × 7 = 5040
Therefore, the probability that all symbols are different is
= 15600 × 5040 / 175760000
= 0.45 approximately
(b) The probability that all symbols are different and the first number is the largest among the numbers.
The probability that first number is largest among the numbers is = 3!/4! = 1/4
The probability that all symbols are different is 0.45 approximately
Therefore, the required probability is
= 1/4 of 0.45
= 0.11 approximately.

What is Pascal's law statement?
Pascal's law statement states that pressure is equal to the force divided by the area on which it acts.
What is Pascal's law statement?According to Pascal's law, pressure applied to a fluid inside of a container will be transmitted without a change in magnitude to every point within the fluid as well as the container's walls. Any point in the fluid experiences equal pressure in all directions.
The force multiplied by the surface area on which it acts produces pressure. Pascal's principle states that a pressure increase on one piston in a hydraulic system causes an equal increase in pressure on another piston in the system.

What is equidistant from a fixed point?
A set of points equidistant from a fixed point in a plane figure is called a circle where the distance between each of the set of the points and the fixed point forms the radius of the circle.
A point is said to be equidistant from a set of objects if the distances between that point and each object in the set are equal.
In two-dimensional Euclidean geometry, the locus of points equidistant from two given (different) points is their perpendicular bisector. In three dimensions, the locus of points equidistant from two given points is a plane, and generalising further, in n-dimensional space the locus of points equidistant from two points in n-space is an (n−1)-space.

Step-by-step explanation:
The volume of a ball:
[tex]\displaystyle\\V=\frac{4}{3} \pi R^3[/tex]
Let us calculate the volume of a big metallic ball:
[tex]\displaystyle\\V_{big}=\frac{4}{3} (3)(3^3)\\\\ V_{big}=4(27)\\\\V_{big}=108 \ cm^3[/tex]

How do you find the nature of roots with examples?
The nature of the roots of a quadratic equation is known by a value known as the discriminant, which is calculated by seeing the equation and comparing it with the standard equation which is given by -
ax^2 + bx +c , where a , b , c are constants .
The root of the equation is given by -
x= [(-b )± (b^2 - 4ac)] / 2a
Here, the term (b^2 - 4ac) is called the discriminant of the quadratic equation .
This discriminant is the defining factor of the nature of the roots.
Now, here arise three cases-
(i) If (b^2 - 4ac) > 0, the roots are real and distinct .
(ii) If (b^2 - 4ac) = 0 , the roots are real and equal.
(iii) If (b^2 - 4ac) < 0 , the roots are not real and they are imaginary i.e. they are complex in nature and of the form a+ib.
For example , we have an equation x^2 + 2x + 1.
Here, a =1, b=2 and c=1.
Putting these values in the discriminant , we get -
b^2 - 4ac = 4-4(1)(1) = 0.
So, the roots of the equation are real and equal i.e. x=2,2.
Hence, it is the discriminant which determines the nature of roots.

Can a person draw Social Security and disability at the same time?
Generally it is not possible. But if someone applying for early retirement after being forced to leave their jobs due to an illness or injury. In order to help them pay their costs until their SSDI claim is approved and the waiting period for those benefits has passed, they can start collecting early retirement payments.
Generally speaking, it is not possible to receive both Social Security retirement benefits and Social Security Disability Insurance (SSDI) at the same time. However, if you fulfill the severe financial requirements while receiving SSDI or retirement payments from Social Security, you can be eligible for Supplemental Security Income (SSI).
To fill the gap between when someone must leave the working due to a disability and when they can receive retirement benefits, the Social Security Administration (SSA) established the SSDI program. Because of this, there is only one option to get SSDI and retirement benefits at the same time.
This happens when a person chooses to retire early between the ages of 62 and their full retirement age but is later granted SSDI payments. Some people do this on purpose by applying for early retirement after being forced to leave their jobs due to an illness or injury.

This meal costs $17.00. a 7% sales tax is applied, followed by an automatic tip of 18%. what is the total with tax and tip?
The total cost for the meal with tax and tip is $22.26.
This can be calculated using the following formula:
Total Cost with Tax and Tip = Meal Cost + (Meal Cost * Sales Tax Rate) + (Meal Cost * Tip Rate)
In this case, the formula would be:
Total Cost with Tax and Tip = 17.00 + (17.00 * 0.07) + (17.00 * 0.18)
This simplifies to:
Total Cost with Tax and Tip = 17.00 + 1.19 + 3.06
Which yields a final total cost of 22.26.
To explain in more detail, the meal cost is the original cost of the meal, which in this case is 17.00. Then, the sales tax rate is applied to the meal cost, which is 7% or 0.07. This gives us an additional cost of 1.19 (17.00 * 0.07). Lastly, the tip rate is applied to the meal cost, which is 18% or 0.18. This gives us an additional cost of 3.06 (17.00 * 0.18). Adding the meal cost of 17.00, the tax cost of 1.19, and the tip cost of 3.06 together gives us a total cost of 22.26.
Therefore, the total cost for the meal with tax and tip is $22.26.

What are the 12 types of sets?
The 12 types of sets are empty set, singleton set, finite set, infinite set, subset, equal set, universal set, power set, proper subset, superset, equivalent set and proper superset.
An empty set does not contain any element, while a singleton set contain only one element.
If the number of elements in a set is finite, the set is a finite set. If the number of elements in a set is not finite, that is not countable it is an infinite set.
A set, say A contain only elements of another set, say B but not necessarily all elements, than set A is a subset of set B.
Whenever a set A is a subset of set B, we say the B is a superset of A. If A and B are two sets, then A is called the proper subset of B if A is a subset of B but B is not a subset of A i.e., A ≠ B.
If a set contains all and only elements of another set, then both set are said to be equal sets.
A universal set contains all elements of related sets.
Power set is the collection of all subsets of a particular set.
The set B is the proper superset of set A, then all the elements of set A are in B, but set B must contain at least one element which is not present in set A.

What is the nature of roots of x² 6x 9?
The equation x² + 6x + 9 has two real roots, because the discriminant (b² - 4ac) is greater than zero. The two roots can be calculated using the quadratic formula.
The equation x² + 6x + 9 has two real roots, because the discriminant (b² - 4ac) is greater than zero. This can be seen by calculating b² - 4ac, which in this case gives (6² - 4*1*9) = 36 - 36 = 0. A discriminant of zero or higher means that the equation has two real roots. The two roots can be calculated using the quadratic formula, which is x = [-b ± Â√(b² - 4ac)] / 2a. In this case, a = 1, b = 6, and c = 9, so the formula becomes x = [-6 ± Â√(6² - 4*1*9)] / 2, which simplifies to x = [-6 ± Â√0] / 2, or x = [-6 ± 0] / 2. So the two roots are x = -3 and x = -3, which means that the equation has two equal real roots.
x² + 6x + 9
b² - 4ac = (6² - 4*1*9) = 36 - 36 = 0
