Explanation / Answer
Answers to the question:
11. P( of getting a man or someone who survived the sinking.)
=P(man) +P(survive) -P(man survived)
=(332+1360+332+318+29+27-332) / (332+1360+318+104+29+35+27+18)
=.93
12.
P( probability of getting a woman or someone who did not survive the sinking.)
=(318+104+1360+35+18)/(332+318+29+27+1360+104+35+18)
=.825
