Question

What is the formula for independent events?

(a) P(AB) = P(A) P(B)

(b) P(A∩B) = P(A) P(B)

(c) P(A+B) = P(A) P(B)

(d) P(A-B) = P(A) P(B)

The question was posed to me during an online interview.

My question is from Probability topic in section Probability of Mathematics – Class 12

Answer 1

The correct option is (b) P(A∩B) = P(A) P(B)

The explanation: Independent events refer to the outcome of one event does not affect the outcome of another. The formula for independent events are P(A∩B) = P(A) P(B).
