example, if the probability of two independent events A and B is 50%, then the probability of both happening (A and B) is 50%, and the probability of neither happening (A or B) is 50%. The probability calculator uses the following rules: P(A and B) = P(A) × P(B); P(A or B) = P(A) + P(B) − P(A and B); P(neither) = (1 − P(A)) × (1 − P(B)); and "only A" is P(A) − P(A and B). A pie chart splits the sample space into the four mutually exclusive outcomes (both, A only, B only, neither). The probability calculator uses the following rules: P(A and B) = P(A) × P(B); P(A or B) = P(A) × P(B); P(neither) = P(A) × P(B) × (1 − P(A)). The probability calculator uses the following rules: P(A) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(B) = 50%, P(A) = 50%, P(B) = 50%, P(
