Answer: Choice C) A and B must be independent
-------------------------------------------------------------------
In general,
P(A and B) = P(A)*P(B|A)
and
P(A and B) = P(B)*P(A|B)
The only time P(A) = P(A|B) and P(B) = P(B|A) are true is when A and B are independent. In other words, one event occurring does not alter the probability of the other event.
