Suppose there are three events, A, B, and C. You are also given the values of: P(A), P(B), P(C), P(A intersect B), P(B intersect C), P(A intersect C), and P(A intersect B intersect C). How would you find the probability that only event A occurs?

What you want is , probability of A and not B and not C.
I suggest you draw a Venn diagram to see this.
