Question

gaming and the laws of probability. Casino games of pure chance (e.g., craps, roulette, baccarat, and keno) always yield a ?house advantage.? For example, in the game of double?zero roulette, the expected casino win percentage is 5.26% on bets made on whether the outcome will be either black or red. (This percentage implies that for every $5 bet on black or red, the casino will earn a net of about 25 cents.) It can be shown that in 100 roulette plays on black/red, the average casino win percentage is normally distributed with mean 5.26% and standard deviation 10%. Let x represent the average casino win percentage after 100 bets on black/red in double?zero roulette. a. Find P(x > 0). (This is the probability that the casino wins money.) b. Find P(5 < x < 15). c. Find P(x < 1). d. If you observed an average casino win percentage of ?25% after 100 roulette bets on black/red, what would you conclude?
