While playing a certain dice game, Chris wins if the sum of the two dice is 7, at which point the game is over. If the game allows Chris three rolls in an attempt to win, what is the probability that Chris will win?
I could not understand how to approach this problem.
Can someone throw some light on how to solve this.
I understand the solution. But I have a meaning problem:How many dices could be rolled (max)
? Three pairs (6) or three dices (3)
I understand that he rolls the
First dice (from 1 to 6). No thing I can do.
Second dice (1 to 6) = 1/6 of chance of getting a 7.
If the sum is below 7:
Third dice (1 to 6). I dont know how to calculate! =)
My final question is: is this problem ambiguous?
