Step 1: Doyle, a professional poker player, is at the poker table. As he sits at the table looking at his hand and at the upturned cards on the table, Doyle has seen 24 cards, and the only hearts are the 2 in his hand. None of other players have any hearts. The full deck contains 13 hearts among its 52 cards. Doyle is hoping the next three cards dealt to him will be hearts. This outcome would give him...

A fair die has the numbers 1, 2, 3, 4, 5, and 6 on its faces. Each face is equally likely to come up on a roll. You are conducting an experiment. You roll the die and record the number rolled. Then you roll the die again and add this second number to the first numbered rolled. The outcome of the experiment is this sum. List all of the possibilities for outcomes of this experiment?

In a lottery game, a player picks 4 numbers from 1 to 46. If 2 of those 4 numbers match those drawn, the player wins third prize. Let's walk through the steps to determine the probability of winning third prize. In how many ways can 2 winning numbers be chosen from the possible 4 numbers? In how many ways can 2 non-winning numbers be chosen from the pool of all non-winning numbers? The number of favorable outcomes would be to...
