WebMar 27, 2024 · Since there are 32 equally likely outcomes, each has probability 1 32, so P ( O c) = 1 ∕ 32, hence P ( O) = 1 − 1 32 ≈ 0.97 or about a 97 % chance. Intersection of Events Definition: intersections The intersection of events A and B, denoted A ∩ B, is the collection of all outcomes that are elements of both of the sets A and B.
