Answer:
Denote:
Probability that he eats pizza for dinner: P(A) = 40% = 0.4
Probability that he drinks Cola: P(B)
Probability that he will drink Cola, given he ate pizza: P(B|A) = 80% = 0.8
=> Applying conditional probability formula, probability that he drinks and he eats pizza:
P(A⋂B) = P(B|A) x P(A) = 0.4 x 0.8 = 0.32
=> Option B is correct
Hope this helps!
