How to solve the probability
WebSo the probability = 1 6. The probability of an event is shown using "P": P (A) means "Probability of Event A". The complement is shown by a little mark after the letter such as A' (or sometimes Ac or A ): P (A') means "Probability of the complement of Event A". The two probabilities always add to 1. P (A) + P (A') = 1. WebExample 1: basic probability. A card is chosen at random. Find the probability the card has a letter B on it.
