The last option is correct for two independent events.

P (A and B) = P (A) P (B)

And P (B and A) = P (B) P (A) which is equal. And other three cases are false.

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 (BA)

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 (BA)
