Extracted text: 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 5.34% on bets made on whether the outcome will be either black or red. (This implies that for every $5 bet on black or red, the casino will eam a net of about 34 cents.) It can be shown that in 100 roulette plays on black/red, the average casino win percentage is normally distributed with mean 5.34% and standard deviation 11%. Let x represent the average casino win percentage after 100 bets on black/red in double-zero roulette. Complete parts a through d. a. Find P(x>0).
