Solution

Pr( he died of lung or prostate Cancer)=Pr( he died of lung Cancer)+Pr( he died of prostate Cancer)

=(12026/36155)+(10035/36155)=0.61

Pr( he died of stomach or the pancreas Cancer)=Pr( he died of stomach Cancer)+Pr( he died of pancreas Cancer)

=3037/36155+3031/36155

=0.168

Pr( did not die of lung cancer)=1-Pr( he died of lung Cancer)=1-12026/36155=0.667
