Question

What statements are correct? Check all that apply. The conditional probability formula is P(X │ Y) = StartFraction P (X intersection Y) Over P (Y) EndFraction. The conditional probabilities P(D │ N) and P(N │ D) are equal for any events D and N. The notation P(R │ S) indicates the probability of event R, given that event S has already occurred. Conditional probability applies only to independent events. Conditional probabilities c

Answer 1

The conditional probability formula is P(X|Y) = P (X ∩ Y) / P (Y). Then the correct option is A.

What is conditional probability?

Suppose that the sample space is S. Out of which there are two events, A and B, subsets of S.

Then, we can interpret P(A|B) as the probability of that part of A which is in B, with the new sample space as B. (assuming the probability of B is not 0).

Symbolically, we write it as:

P(A|B) = P(A ∩ B) / P(B)

Then we have

P(X|Y) = P(X ∩ Y) / P(Y)

Thus, the correct option is A.
