Explanation / Answer

Ans:

a)

i)P(oppose)=0.04+0.27+0.02=0.33

ii)P(Y and favor)=0.08

iii)P(X/oppose)=P(oppose and X)/P(oppose)=0.04/0.33=0.12121

b)

P(Y or oppose)=P(Y)+P(oppose)-P(Y and oppose)

Now,

P(Y)=0.08+0.27+0.03=0.38

P(oppose)=0.33

P(Y and oppose)=0.27

So,

P(Y or oppose)=0.38+0.33-0.27=0.44
