Question

4. At Eagle Rock High School, the probability that a student takes theatre and choir is 0.052.

The probability that a student takes choir is 0.17. What is the probability that a student takes theatre given

that the student is taking choir?

a) 2.9 %

b) 30.6%

c) 24.2%

d) 34.4%

Answer 1

B

Explanation:

Conditional probability is:

P(A given B) = P(A and B) / P(B)

Here, P(A and B) = 0.052 and P(B) = 0.17:

P(A given B) = 0.052 / 0.17

P(A given B) = 0.306
