In 1912 the Titanic struck an iceberg and sank on its first voyage. Some passengers got off the ship in lifeboats, but many died. The following two-way table gives information about adult passengers who survived and who died, by class of travel.

Given: ClassSurvived First  Second  Third  Total  Yes 19794151442 No 122167476765 Total 3192616271207 94+151=245 of the 1207 people on the Titanic were not a passenger in first class and survived. The probability is the number of favorable outromes divided by the number of possible outromes: P(FCandDc)= #of favorable outromes / #of possible outromes=2451207∼−0.2030=20.30%

Suppose we randomly select one of the adult passengers who rode on the Titanic. Find P (not a passenger in first class and survived).
