Webbp(A or B) = p(A) + p(B) - p(A and B). The logic behind this formula is that when p(A) and p(B) are added, the occasions on which A and B both occur are counted twice. To adjust for this, p(A and B) is subtracted. What is the probability that a card selected from a deck will be either an ace or a spade?

When we assume that, let’s say, x be the chances of happening an event then at the same time (1-x) are the chances for “not happening” of an event.
