SLOT MACHINES Refer to Exercise 37, Section 6.3, in which the "lucky dollar" slot machine was described. What is the probability that the three "lucky dollar" symbols will appear in the window of the slot machine?
SLOT MACHINES A “lucky dollar” is one of the nine symbols printed on each reel of a slot machine with three reels. A player receives one of the various payouts whenever one or more “lucky dollars” appear in the window of the machine. Find the number of winning combinations for which the machine gives a payoff.

- Roulette American roulette is a game in which a wheel turns on a spindle and is divided into 38 pockets. Thirty-six of the pockets are numbered 1-36, of which half are red and half are black. Two of the pockets are green and are numbered 0 and 00 (see figure). The dealer spins the wheel and a small ball in opposite directions. As the ball slows to a stop, it has an equal probability of landing in any of the numbered pockets. (a) Find the probability of landing in the number 00 pocket. (b) Find the probability of landing in a red pocket. (c) Find the probability of landing in a green pocket or a black pocket. (d) Find the probability of landing in the number 14 pocket on two consecutive spins. (e) Find the probability of landing in a red pocket on three consecutive spins.arrow_forwardFind the probability of each event.
