Question

The following data represent the survival data for the ill-fated Titanic voyage by gender. The males are adult males and the female arc adult females. Write your answer in fraction and decimal with three places. Suppose a passenger is selected at random, find the following probabilities. a) What is the probability that the passenger survived? b) What is the probability that the passenger was male? c) What is the probability that the passenger was female or a child? d) What is the probability that the passenger female and survived? e) What is the probability that the passenger was male or survived? f) If a female passenger is selected at random, what is the probability that she survived? g) If a child passenger is selected at random, what is the probability that the child died? h) What is the probability that the passenger is survived given that selected is male? i) What is the probability that the passenger is female given that selected was died? A blood bank catalogs the types of blood, including positive or negative Rh-factor, given by donors during the last five days. The number of donors who gave each blood type is shown in the table. If one subject is randomly selected, find the probability of the following events. Write your answer: first as a fraction then in decimal with two places a) The donor's Rh-factor is negative. b) The donor has "B" blood type and positive Rh-factor. c) The donor "AB" blood type or has negative Rh-factor. d) The donor has positive Rh-factor given that the donor is "O" type. The US. senate Appropriations Committee has 29 members and a subcommittee is to be formed by randomly selecting 5 of its members. How many different committees could be formed?

Explanation / Answer

14. a) P(Rh-factor is negative) = 70/424 = 0.17

b) P(B blood type and positive Rh-factor) = 37/424 = 0.09

c) P(AB blood type or negative Rh-factor) = (70+22)/424 = 92/424 = 0.22

d) P(positive Rh-factor | O type) = 156/354 = 0.44

15. Number of committees that could be formed = 29C5 = 29! / (5! x 24!) = 118,755
