Brief introduction to Conditional Probability
What is the probability of an event A given that event B has occurred? We call this conditional probability, and it is governed by the formula that P(A|B) which reads "probability of A given B" is equal to the P(A intersect B)/P(B).

Example:
Assume that 75% of the AP Stats students studied for the test. If 40% of those who studied got an A, but only 10% of those who don't study get an A. What is the probability that someone who gets an A actually studied for the test?
