QUESTION 9
P(A) =
P(A) = Number of fishers with a license at Clearwater / Total number of fishers at Clearwater
P(A) = 72 / (72 + 18) = 72 / 90 = 4/5
P(B) = Probability that the fisher chosen from Mountain View did not have a license.
P(B) = Number of fishers without a license at Mountain View / Total number of fishers at Mountain View P(B) = 10 / (10 + 90) = 10 / 100 = 1/10
P(A and B) = P(A) * P(B) = (4/5) * (1/10) = 4/50 = 2/25
