A bet on "black" in Roulette has a probability of 18/38 of winning. If you win, you double your money. You can bet anywhere from $1 to $100 on each spin. a. Suppose you have $10, and are going to play until you go broke or have $20. What is your best strategy for playing? Explain using information you learned in this module's material, such as expected value. b. Suppose you have $10, and are going to play until you...
Problem 1. Suppose we are betting money on the outcome of a game of chance with two outcomes (e.g. roulette). If we guess correctly we get double our bet back and otherwise we lose the money we've bet. Consider the strategy where you initially bet one euro and you keep playing and doubling your bet until the first time you win. At that point you go home, having made a net profit. Let p be the probability of winning a...
In the game of roulette, a player can place a $10 bet on the number 6 and have a 1/38 probability of winning. If the metal ball lands on 6, the player gets to keep the $10 paid to play the game and the player is awarded an additional $350. Otherwise, the player is awarded nothing and the casino takes the player's $10. What is the expected value of the game to the player? If you played the game 1000...
You are playing roulette and keep betting on black with a probability of 18/38. You decide you are going to quit playing after losing 10 times. What is the probability that you quit after the 23rd game? Also, is this discrete or continuous?
On a roulette wheel, there are 38 slots, 18 of which are colored black. If you bet $5 on black and win, you get $10 back. If black doesn’t come up, you lose your $5. Find the expected value of playing the game 100 times.
You play roulette betting one dollar on the number 5 each time. The bet pays 35 to 1. You have a 1 in 38 chance to win. On average, you will lose playing this game and each play will cost you approximately _____ cents. (Round to the nearest cent) Suppose you play roulette 64 times, betting a dollar on the number 5 each time, your expected net gain is______ dollars. Using the short-cut, the SD for the box model is...
A roulette wheel has 38 numbers, with 18 odd numbers (black) and 18 even numbers (red), as well as 0 and 00 (which are green). If you bet $19 that the outcome is an odd number, the probability of losing the $19 is 20/38 and the probability of winning is $38 (for a net gain of only $19, given you already paid $19) is 18/38. If a player bets $19 that the outcome is an odd number, what is the...
2. An American roulette wheel contains 38 numbers: 18 are red, 18 are black, and 2 are green. When the roulette wheel is spun, the ball is equally likely to land on any of the 38 numbers. Suppose that you bet $1 on red. If the ball lands on a red number, you win $1; otherwise you lose your $1. Let X be the amount you win on your $1 bet. (b) Find the expected value of the random| variable...
4. Suppose you wish to bet on an event with the probability 0.8 of happening. At what payout odds would it be a fair bet? 5. Suppose there are two players at a roulette table. The first player wagers $5 on BLACK and thesecond player wagers $10 on a 6 NUMBER bet. What is the casino’s expected total gain from the spin?

Otherwise, the player is awarded nothing and the casino takes the player's $9. What is the expected value of the game to the player? If you played the game 1000...
