Answer:

OPTION A: $ \frac{11}{20} $

Step-by-step explanation:

$ P(A | B) = \frac{P(A \cap B)}{P(B)} $

$ P(not B) = 1 - P(B) = 1 - \frac{13}{20} = \frac{7}{20} $

$ \implies P(A \cap B)= P(A | B) \times P(B)  $

$ = \frac{11}{20} \times \frac{7}{20} $

Let us keep it without multiplying for easy simplification later.

Also, let us assume A and B are independent events.

$ P(A \cap B) = P(A) \times P(B) $

$ \implies \frac{11}{20} \times \frac{7}{20} = P(A) \times \frac{7}{20} $

$ \implies P(A) = \frac{11}{20} $

Hence, OPTION A 11/20 is the answer.

 For example:
 ax^2
 It is a monomial.
 In this case we have the following expression:
 18x
 Using the given definition, we have that the expression is a monomial.

Anita plans to give her husband 3 shirts for his birthday. She narrows the search to 3 shirts from a selection of 17 shirts at D
Lunna [17]

Using the combination formula, it is found that she can select the shirts in 775,200 ways.

The order in which the shirt are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.

Combination formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem:

  • 3 shirts from a set of 17.
  • Then, 3 shirts from a set of 20.
  • They are independent, hence, to find the total, we multiply both combinations.

T = C_{17,3} \times C_{20,3} = \frac{17!}{3!14!} \times \frac{20!}{3!17!} = 680 \times 1140 = 775200

She can select the shirts in 775,200 ways.
