Total 30 18 19 29 96 Heels Sandals Sneakers Boots 12 Fall Spring Summer Winter Total 10 23 47 21 a. One student is selected. What is the probability that a randomly selected student likes winter or likes boots? b One student is selected. What is the probability that a randomly selected student likes summer, given they like sandals? c. Suppose that two students are chosen with replacement. What is the probability that they both like fall? d. Suppose that two students are chosen without replacement. What is the probability that they both like sneakers and the summer at the same time?

Explanation / Answer

a) P(likes winters or boots) = (29+8+3+3)/96 = 0.4479

b) P(summer/Sandals) = 5/23 = 0.2174

c) P(both like fall) = (30/96)*(30/96) = 0.0977

d) P(Sneakers and Summer) = (56/96)*(55/95) = 0.3377
