Question

If two events. A and B, are independent then which of the following is always true about their probabilities?

1) P(A)=P(B)
2) P(A and B)=P(A) P(B)
3) P(A OR B)=P(A) P(B) - P(A and B)
4) P(A and B) = P(A) +P(B)​

Answer 1

P(A and B)= p(A) * P(B)

Explanation:

The Formula for the probability of A and B (independent events) is

p(A and B) = p(A) * p(B).

Answer 2

The answer I think is 4?
