Please answer question number 4 using the chart provided. Disregard work already written. Thank you.

Answer 1

4)

	first class	2nd class	3rd class	Crew	total
survived	201	118	181	212	712
died	123	166	528	672	1489
total	324	284	709	884	2201

hence P(survive given first class)=(201/324)=0.6204 ~ 62.04%

P(survive given 2nd class)=(118/284)=0.4155~41.55%

P(survive given 3rd class)=(181/709)=0.2553~ 25.53%

P(survive given crew member)=(212/884)=0.2398~ 23.98%

here we can see that probability of a person surviving is highest given person board on first class
