Here, `P(A) = 0.3 and P(B) = 0.4`
(i) `P(AnnB) =P(A).P(B) = 0.3**0.4 = 0.12 `
(ii) `P(AuuB) = P(A)+P(B)-P(AnnB) = 0.3+0.4-0.12 = 0.58`
(iii)As, A and B are independent events, `P(A|B)` will be equal to `P(A)`. So,
`P(A|B) = P(A) = 0.3`
(iii)As, A and B are independent events, `P(B|A)` will be equal to `P(B)`. So,
`P(B|A) = P(B) = 0.4`
