P(Alice wins) =P(Alice roll a 6 in first attempt)+P(Alice and Bob do not roll a 6 on first attempt and Alice roll on 2nd)+............
=(1/6)+(5/6)*(5/6)*(1/6)+(5/6)*(5/6)*(5/6)*(5/6)*(1/6)+..............
=(1/6)/(1-(5/6)2) =6/11 =0.5455 ( as sum of infinite geometric series is a/(1-r))

Bob and Doug are playing the following game. Bob starts by rolling two fair dice; if the sum of his dice is six, then he wins the game. If not, then Doug rolls the dice, and if the sum of his rolls is seven, then he wins the game. If neither player wins the game during the first round, then they repeat the process (with Bob going first) until someone wins a round. What is the probability that Bob wins...

You and a friend are playing a game. You alternate turns rolling a single die, and the first person to roll a 1 or a 2 wins. Your friend goes first. a. What’s the probability that the game ends in three rolls or fewer? b. What’s the expected number of rolls? c. What’s the probability that your friend wins?

1 point) Three brothers play a game with a pair of fair (six-sided) dice. Scott will win if the sum of the dice is 3, Dave will win if 9, and Jim if 11 They will roll the die until a winner is declared Part (c) Realizing this, theoretically, is a game that could go on forever..the three brothers decide that if no winner has been decided in three rolls or "turns" Scott will be deemed the winner. Let Y...

Suppose you are rolling a fair four-sided die and a fair six-sided die and you are counting the number of ones that come up. What is the probability that both die roll ones? What is the probability that exactly one die rolls a one? What is the probability that neither die rolls a one? What is the expected number of ones? If you did this 1000 times, approximately how many times would you expect that exactly one die would roll...

Problem 2: Tails and (Heads or Tails?) Alice and Bob play a coin-tossing game. A fair coin (that is a coin with equal probability of 1. The coin lands 'tails-tails' (that is, a tails is immediately followed by a tails) for the first 2. The coin lands 'tails-heads (that is, a tails is immediately followed by a heads) for the landing heads and tails) is tossed repeatedly until one of the following happens time. In this case Alice wins. first...

In a certain board game, a player rolls two fair six-sided dice until the player rolls doubles (where the value on each die is the same). The probability of rolling doubles with one roll of two fair six-sided dice is 16
Suppose Jane has a fair 4-sided die, and Dick has a fair 6-sided die.
1. Suppose Jane has a fair 4-sided die, and Dick has a fair 6-sided die. Each day,they roll their dice (independently) until someone rolls a “1”. (Then the personwho did not roll a “1” does the dishes.) Find the probability that …a) they roll the first “1” at the same time (after equal number of attempts);b) it takes Dick twice as many attempts as it does Jane to roll the first “1”;c) Dick rolls the first “1” before Jane does.
