Write your answer in fraction and decimal with assenger Male Female Child Total Survived 338 316 Died Total 57 52 1352 109 Suppose a passenger is selected at random. a) Complete the table above. b) What is the probability that the passenger survived? c) What is the probability that the passenger was female? d) What is the probability that the passenger was female or a child? e) 0) What is the probability that the passenger was male or survived? 8) If a female passenger is selected at random, what is the probability that she died? h) If a child passenger is selected at random, what is the probability that the child survived? i) What is the probability that the passenger is survived given that selected is male? j) Suppose two females are randomly selected. What is the probability both survived? W hat is the probability that the passenger female and survived?

Explanation / Answer

6. a)

b) P(survived) = 711/2224 = 0.3197

c) P(female) = 425/2224 = 0.1911

d) P(female or child) = (425+109)/2224 = 0.2401

e) P(female and survived) = 316/2224 = 0.1421

f) P(male or survived) = (711+1352)/2224 = 0.9276

g) P(died | female) = 109/425 = 0.2565

h) P(survived | child) = 57/109 = 0.5229

i) P(survived | male) = 338/1690 = 0.2000

j) P(both females survived) = (316/425)(315/424) = 0.5524

P.S - Please post different questions separately
