Question

Suppose a passenger is selected at random. a) What is the probability that the passenger survived? b) What is the probability that the passenger was female? 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 female and child? f) What is the probability that the passenger was female or survived? g) If a female passenger is selected at random, what is the probability that she survived? 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?

Explanation / Answer

10) probability =(4/52)*(3/51)*(2/50) =0.00018

11)probabilty =1/(43*42*41*40*39)= 1/115511760

12)a) probability =711/2224

b)probability =425/2224

c)=(425+109)/2254 =534/2254

d)=316/2254

e)0

f)=(425+338+57)/2254 =820/2254

g)=316/425

h)=57/109

i)=338/1690

j)=(316/425)*(315/424)=0.5524
