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 workWorked example: with P(A) = 50% and P(B) = 50%, both happen with probability 0.5 × 0.3 = 65%, and neither happens with probability 0.5 × 0.7 = 35%.
