Probability of an event made of two or more sample events is the sum of their probabilities. Cold some one give me example for this. Thank you in advance

We know that P( A or B) = P( A ) + P ( B ) - P ( A and B ) = P (A ) + P ( B ) only when P ( A and B ) = 0. Can you think of two simple events A and B such that P ( A and B ) = 0??
