Probability 0.0 / 5 ? MathematicsStatistics, averages and distributionsASOCR Created by: maddieCreated on: 14-05-15 14:26 Probability Probability of A or B happening P(AuB)=P(A) + P(B) - P(AnB) Mutually Exclusive P(AuB)=P(A) + P(B) (as the two circles dont intersect) Conditional Probablilty P(A/B)=P(AnB) P(B) P(A/B) = P(A) --> independent Discrete random probability distribution is best illustrated by a vertical line chart. E(x) = = Σ(values x probability) Var (x) = = Σ(values² x probablily) - mean² 1 of 1
