Unformatted text preview: Rule of Multiplication If events A and B come from the same sample space, the probability that both A and B occur is equal to the probability the event A occurs times the probability that B occurs, given that A has occurred P(A ∩ B) = P(A) P(B|A). Rule of Addition If events A and B come from the same sample space, the probability that event A and/or event B occur is equal to the probability that event A occurs plus the probability that event B occurs minus the probability that both events A and B occur P(A ∪ B) = P(A) + P(B) - P(A ∩ B). Symbols: P(A ∩ B) (both A and B), P(A ∪ B) (union, either A or B can occur) Chapter 4 Discrete: countable, Continuous: infinite; can’t count)...
