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 (j). (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.) (d) If a passenger is selected at random, what is the probability that the passenger was female and survived? (Round to three decimal places as needed.) (e) If a passenger is selected at random, what is the probability that the passenger was female or survived? (Round to three decimal places as needed.)

Explanation / Answer

C)

Out of 2312 passengers, 620 are female and 152 are child

So the probability that the passenger was female or a child is

P(female or child) = (620 + 152) / 2312 = 772 / 2312 = 0.334

d) There are 470 Passengers are female and survived.

P(Female and survived) = 470/2312 = 0.203

e) There are 620 are Female and 832 are survived.

P(Female or survived) = (620 + 832)/2312 = 0.628
