Probability of both a and b

WebbIf two events A and B are not disjoint, then the probability of their union (the event that A or B occurs) is equal to the sum of their probabilities minus the sum of their intersection. P(A) + P(B) - P(A and B) = 3/5 + 2/5 - 6/25 = 1 - 6/25 = 19/25 = 0.76. For another example, consider tossing two coins.
