.

For your info: the probability values NEVER are greater than 1.

If P%28A%29=+7, P%28B%29+=+45 and P(A and B) = 2
Basic Probability Rules:
Probability Rule One (For any event A, 0+%3C=+P%28A%29+%3C=1); so it's not possible to have P%28A%29=+7, P%28B%29+=+45
Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
Probability Rule Three (The Complement Rule)
Probabilities Involving Multiple Events.
Probability Rule Four (Addition Rule for Disjoint Events)
Finding P(A and B) using Logic.
