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

aleksklad [387]

Answer:

Step-by-step 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
