Explanatory Notes for Teachers: 1. An experiment consists of drawing one card from a well shuffled deck of 52 cards. When two events (call them "A" and "B") are Mutually Exclusive it is impossiblefor them to happen together: P(A and B) = 0 "The probability of A and B together equals 0 (impossible)" But, for Mutually Exclusive events, the probability of A orB is the sum of the individual probabilities: P(A or B) = P(A) + P(B) "The probability of A or B equals the probability of A plusthe probability of B" So, we have: 1.
