(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.)
(f) If a female passenger is selected at random, what is the probability that she survived?
(Round to three decimal places as needed.)
(g) If a child passenger is selected at random, what is the probability that the child survived?
(Round to three decimal places as needed.)
(h) If a male passenger is selected at random, what is the probability that he survived?
(Round to three decimal places as needed.)
(i) Do you think the adage "women and children first" was adhered to on this ship?
A. No, because the survival rate for men was about the same as the survival rates for women and children.
B. No, because the survival rate for men was higher than the survival rates for women and children.
O C. Yes, because the survival rate for men was much lower than the survival rates for women and children.
(j) Suppose two females are randomly selected. What is the probability both survived?
(Round to four decimal places as needed.)
