A game works as follows: the player rolls one dice once (let's call it ''n'') and then he rolls it second time (let's call this second roll "m'') and receives nm points .

A)What is the probability that n = 1 knowing that the player has received more than 20 points.
b) What is the probability that m = 1 knowing that the player has received more than 20 points.
c) (What is the probability that the player receives more than 20 points?
d) Let X be the following random variable: X = n knowing that the player has received more than 20 points. Give the probability of X.

A game works as follows: each player rolls one dice (let's call it ''n''). After both players have made the first roll, they have the choice to leave or not. If a player exits, he automatically looses; if not, he rolls a second time (let's call this second roll "m'') and receives nm points . The player with the most points wins, in case of a tie no one wins. a) Give the fundamental space of the two throws. b)...

In a dice game a player first rolls two dice. If the two numbers are l ≤ m then he wins if the third roll n has l≤n≤m. In words if he rolls a 5 and a 2, then he wins if the third roll is 2,3,4, or 5, while if he rolls two 4’s his only chance of winning is to roll another 4. What is the probability he wins?

In the game of Lucky Sevens, the player rolls a pair of dice. If the dots add up to 7, the player wins $4; otherwise, the player loses $1. Suppose that, to entice the gullible, a casino tells players that there are lots of ways to win: (1, 6), (2, 5), and so on. A little mathematical analysis reveals that there are not enough ways to win to make the game worthwhile; however, because many people’s eyes glaze over at...

PROGRAMMING IN C-DICE GAME Q1. A player rolls two dice at the same time. Each die has six faces, which contain 1, 2, 3, 4, 5 and 6 spots. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. (i) If the sum is 2 or 10 on the first throw, the player wins. (ii) If the sum is 3, 7 or 12 on the first throw, the player loses. (iii)...

In the game of craps, a player (known as the shooter) rolls two fair six-sided dice. The shooter immediately loses if the sum of the dice is 2, 3, or 12 and immediately wins if the sum of the dice is 7 or 11 on the first roll. If the sum is anything else (4, 5, 6, 8, 9, or 10), that number becomes the point and the shooter rolls again. The shooter now wins by rolling that same point...

At a charity event, a player rolls a pair of dice. If the player roles a pair (same number on each die), the player wins $10. If the two are exactly one number a part (like a five and a six), the player wins $6. IF the player roles a one and a six, they win $15. Otherwise, they lose. If it cost $5 to play, find the expected value. Write a complete sentence to explain what your answer means...
