Suppose you are playing a game of Yahtzee. You know that you play with 5 dice, each with 6 sides. Since the dice are all rolled at the same time, let the roll (5, 4, 3, 2, 1) to be equal to (2, 4, 5, 1, 3). Assume for this question that we will only be rolling the dice once. (i) How many ways can you roll all the dice? (ii) To win 50 points you would need all the dice to roll the same number (ex. (1, 1, 1, 1, 1)). How many ways can you win the 50 points? (iii) Suppose you are trying to get your dice to roll only consecutive numbers (ex. (1, 2, 3, 4, 5) or (2, 3, 4, 5, 6)) How many different ways are there to do this? (iv) Suppose instead you are trying to get your dice to roll 4 consecutive numbers (ex. (1, 2, 3, 4, 1) or (2, 3, 4, 5, 3)) How many different ways are there to do this? (make sure to not count any only consecutive numbers) This is a combinatorics math counting problem.

In a game, two coins are tossed. If either of the coins comes up heads, you have won a prize. To claim the prize, you must point to one of your coins that is a head and say 'look, that coin's a head, I've won'. You watch Fred play the game. He tosses the two coins, and he points to a coin and says 'look, that coin's a head, I've won'. What is the probability that the other coin is a head?
Pest Control In an experiment to test the effectiveness of the latest roach trap, the "Roach Resort," 500 roaches were placed in the vicinity of the trap and left there for an hour. At the end of the hour, it was observed that 20 of them had "checked in," while the rest were still scurrying around. (Remember that "once a roach checks in, it never checks out." Let 1 not checked in, and 2 = checked in.) (a) Set up the transition matrix P for the system with decimal entries. 0.96 0 Calculate p² 0.9216 0 0.04 1 0.0784 1 Calculate p3 0.884736 0 0.1168 x 1 (b) If a roach begins outside the "Resort," what is the probability of it "checking in" by the end of 1 hour? 2 hours? 3 hours? 1 hour 0.04 2 hours 0.0784 3 hours 0.1168 (c) What do you expect to be the long-term impact on the number of roaches? Eventually, all the roaches will have checked in. Eventually, all the roaches will not have checked in. There is not enough information.
