FindAB

andP(AB).

The symbolrepresents the intersection of events. The intersection of two eventsAandBresults in an event that contains only the sample points that are contained in both eventAand eventB. Therefore,AB

is a new event that lists only the sample points that are contained in both eventAand eventB. Recall the set notation used for an event withksample points.

event = {sample point 1, sample point 2,, sample pointk}

EventAis made up of the sample pointsE₁,E₄, andE₆and eventBis made up of the sample pointsE₂,E₄, andE₇. Thus, the intersection of eventsAandBwill have the sample points contained in bothAandB. Choose the points.
