Question:

Match List-I with List-II. Given $P(A)=\frac{1}{3}$ and $P(B)=\frac{1}{5}$ where A and B are independent.

List-I List-II
(A) P(A ∩ B) (I) $\frac{7}{15}$
(B) P(A' ∩ B') (II) $\frac{2}{5}$
(C) P(at least one of the two events takes place) (III) $\frac{1}{15}$
(D) P(only one vent takes place) (IV) $\frac{8}{15}$

Choose the correct answer from the options given below :

Options:

(A)-(I), (B)-(II), (C)-(III), (D)-(IV)

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

(A)-(II), (B)-(III), (C)-(IV), (D)-(I)

(A)-(IV), (B)-(III), (C)-(I), (D)-(II)

Correct Answer:

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Explanation:

The correct answer is Option (2) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

(A) $P(A∩B)=P(A)P(B)=\frac{1}{15}$ (III)

(B) $P(\overline A∩\overline B)=P(\overline A)P(\overline B)=\frac{8}{15}$ (IV)

(C) P(atleast one) = $P(A∪B)=P(A)+P(B)-P(A∩B)=\frac{7}{15}$ (I)

(D) P(only one) = $P(A∪B)-P(A∩B)=\frac{2}{5}$ (II)
