Document Summary

Two events, a and b, are disjoint if they do not have any common outcomes: intersection of two event. The intersection of a and b consists of outcomes that are in both a and b, denoted by a b: union of two event. The union of a and b consists of outcomes that are in a or. P(a b) = p(a) + p(b) p(a b). If the events are disjoint, then p(a b)=0, so. Consider the reading habits of the 1070 class. 30% of the class students read usa today daily, 40% read salt. Lake tribune daily and 10% read both of them daily, what is the percentage of the 1070 class students who do not read these two newspapers daily: independent trials. Di erent trials of a random phenomenon are independent if the outcome of any one trial is not a ected by the outcome of any other trial: multiplication rule.
