Each option is only used once. A bag of marbles is full of half red marbles and half yellow ones. For a game of chance, a marble is randomly selected from the bags 3 times in a row (replacing it after each draw) Winning requires getting exactly two yellow marbles. The following are the patterns that could have occurred: RRR, RRY, RYR, YRR, RYY, YRY, YYR, YYY What actually happened is that someone drew a red, then a yellow, then another red. three marbles being drawn from the bag a chance experiment getting exactly two yellow marbles an outcome RRR, RRY, RYR, YRR, RYY, YRY, YYR, YYY the sample space an event drawing R, Y, R
