Explanation / Answer

Solution:-
9) P(A) = probability that student is taking calculus

P(B) = probability that student is on the dean's list

P(AB) = P(A B) / P(B)

P(A B) = 0.067

P(B) = 0.32

P(AB) = 0.067 / 0.32

P(AB) = 0.2094
---------------------------

10) Given that p = 0.26, n = 4

Part 1) P(all 4 get enough daily exercise) = 0.0046

Part 2) P(at least 1 gets enough exercive) = 0.7001
