Question

(URGENT)

From the sample space S = a single number is to be selected at random. Given the following events, find the indicated probability.

A: The selected number is even.

B: The selected number is a multiple of 4.

C: The selected number is a prime number.

P(Aand B)

P(A and B) =

(Simplify your answer.)

Answer 1

P(A and B) = 1/5 = 0.2

Explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we want to find the probability of taking a number that is even and a multiple of 4.

We have the following sample space, of five numbers: {1,2,3,4,15}.

One of these numbers, 4, is even and a multipled of 4.

P(A and B)

1 out of 5. So

P(A and B) = 1/5 = 0.2
