Document Summary
1: event a and event b are mutually exclusive. Pr[a or b] = pr[a] + pr[b] pr[a and b] = 0. 3+0. 4-0. 2=0. 5. What does that mean? the occurrence of one does not in any way affect the probability that the other will also occur. You flip one unbiased coin, and roll one six sided die. The probability of 1 event may depend on the outcome of another event. The probability of that event occurring, given that a condition is met. Pr[a|b] = probability of a given b is true. Pr[infected| female] = probability that the individual is infected, given the. Pr[infected| female] = probability that the individual is infected, given the individual is female = 5/18. If we want to know the overall probability of a particular event, we sum its probability across every possible condition, weighted by the probability of that condition.
