If A and B are two independent events, then which of the following is/are true? (A) $P(A∩B) = 0$ Choose the correct answer from the options given below: |
(B) and (D) only (A) and (C) only (B) only (B) and (C) only |
(B) and (D) only |
The correct answer is Option (1) → (B) and (D) only ** Given: A and B are independent events. (A) $P(A \cap B)=0$ False — independence does NOT imply probability of intersection is zero. (B) $P(A \cup B) = 1 - P(A')P(B')$ True — for independent events, $P(A' \cap B') = P(A')P(B')$ and $P(A \cup B)=1-P(A' \cap B')$. (C) $P(A \cup B)=P(A)P(B)$ False — this is the probability of intersection, not union. (D) $P(A \cap B)=P(A)P(B)$ True — definition of independence. Correct statements: (B) and (D). |
