Question

If events A and B are independent, what must be true?

P(AB) = P(B)
P(AB) = P(A)
P(A) = P(B)
P(AB) = P(BJA)

Answer 1

P(A and B)=P(B∩A) is true

Explanation:

Let A and B are independent events then

`\textrm{P(A\ and\ B)} = \textrm{P(B}\cap \textrm{A)}`

`= \textrm{P(B)}* \textrm{P(A)}`
