Answer #1

as you haven't given any specifics my answer will be based on the above type of roulette. Here you bet on one number and there are 36 equal parts.

Binomial distribution will be used. Let say X represents numbers of success in n trials.

where p is probability of success.


formula will be

A roulette wheel has 38 numbers. Eighteen of the numbers are black, eighteen are red, and two are green. When the wheel is spun, the ball is equally likely to land on any of the 38 numbers. Each spin of the wheel is independent of all other spins of the wheel. One roulette bet is a bet on black—that the ball will stop on one of the black numbers. The payoff for winning a bet on black is $2 for...

In the the casino game of roulette, players make bets based on a wheel with 38 numbered pockets (18 red pockets, 18 black pockets, and two green pockets, labeled 0 and 00). The wheel is then spun one direction and the ball is spun in the opposite direction. Eventually, the ball will land in one of the numbered pockets. The wheel is designed so that the ball has an equal chance of landing in any one of the pockets. Suppose...

You go to the casino and play roulette. You decide to place bets that the ball will land on the number 18. On a roulette wheel there are the numbers 1-36 and 00. Thus, the likelihood that you win any one spin is 1 in 38. You decide to play 20 times, thus you are in binomial land and the potential ersults of your gambling will be drawn from a binomial distribution B(20,1/38). What is the probability that you win:...
