Question

Suppose the data to the right represent the survival data for the a certain ship that sank. The males are adult males and the females are adult females. Complete parts (a) through ). Male Survived 271 Died 1,293 1,584 Female 407 127 534 Child 69 66 135 Total 747 1.486 2,233 (a) If a passenger is selected at random, what is the probability that the passenger survived? (Round to three decimal places as needed.) (b) If a passenger is selected at random, what is the probability that the passenger was female? (Round to three decimal places as needed.) (c) If a passenger is selected at random, what is the probability that the passenger was female or a child? (Round to three decimal places as needed)

Answer 1

a) P(Survived) = 747/2233 = 0.335

b) P(Female) = 534/2233 = 0.239

c) P(Female or child) = 1 - P(Male) = 0.291

d) P(Female and survived) = 407/2233 = 0.182
