You and your opponent both roll a fair die. If you both roll the same number, the game is repeated, otherwise whoever rolls the larger number wins. Let N be the number of times the two dice have to be rolled before the game is decided. (d) Assume that you get paid $10 for winning in the first round, $1 for winning in any other round, and nothing otherwise. Compute your expected winnings.
Answer:
(d) You get paid $10 with probability 5/12 , $1 with probability 1/12 , and 0 otherwise, so your
expected winnings are 51/12.
The answer is there but I don't understand how you get the probability.
Why is the probability 5/12 for winning in the first round? and why is the probability 1/12 for winning in any other round?

Players A and B each roll a fair 6-sided die. The player with the higher score wins ¤1 from the other player. If both players have equal scores, the game is a draw and no one wins anything. i. Let X denote the winnings of player A from one round of this game. State the probability mass function of X. Calculate the expectation E(X) and variance Var(X). ii. What is the conditional probability that player A rolls , given that...

Suppose that in a certain game you roll a die, and get winnings equal to $100 times the amount shown on the die. If you want to, you can roll again up to a total of three times. However, each time you roll again, you forfeit your previous winnings. You decide to take the following strategy: choose a number i, and if you ever get i or above, stop and collect your winnings, otherwise roll again. What is the value...

The Dice game of "Pig" can be played with the following rules. 1. Roll two six-sided dice. Add the face values together. 2. Choose whether to roll the dice again or pass the dice to your opponent. 3. If you pass, then you get to bank any points earned on your turn. Those points become permanent. If you roll again, then add your result to your previous score, but you run the risk of losing all points earned since your...

A friend bets you $100 on a game involving two six-sided dice, one red and one green. You choose the number of times the pair of dice will be rolled. You win if the number of times a red 6 is rolled is at most 2 and the number of times a green 6 is rolled is at least 2. a) How many times should the dice be rolled to maximise your chance of winning? b) With that number of...

The following dice game is offered to you. You may simultaneously roll one red die and three blue dice. The stake is $1. If none of the blue dice matches the red die, you lose your stake; otherwise, you get anyway paid k + 1 dollars if exactly k of the blue dice match the red die. In the case that exactly one blue die matches the red die, you get paid an additional $0.50 if the other two blue...
Craps
Write a C++ game that plays Craps. Craps is a game played with a pair of dice. The shooter (the player with the dice) rolls a pair of dice and the number of spots showing on the two upward faces are added up. If the opening roll (called the ‘come out roll’) is a 7 or 11, the shooter wins the game. If the opening roll results in a 2 (snake eyes), 3 or 12 (box cars), the shooter loses,...

Example Consider the following dice game. A pair of standard ( fair ) dice are repeatedly rolled. If a ’ 7 ’ comes up before an ’ 11 ’ , then the player wins, otherwise the player loses. Let W be the event that the player wins. Find P(W). To say the dice are fair is equivalent to assuming that Laplace’s rule holds and the 36 possible outcomes for a throw of the dice are equally likely. For convenience, an...
