Ashley, Bob, Carol, and Doug are rescued from a desert island by a pirate who forces them to play a game. Each of the four, in alphabetical order by first name, is forced to roll two dice. If the total on the two dice is either 8 or 9, the person rolling the dice is forced to walk the plank. The players go in order until one player loses: A, B, C, D, A, B, ... What is the probability that Doug survives?

There are 4 ways to sum up to 9.

There are 5 ways to sum up to 8. 

There are 36 different rolls on the die, but 9 ways to die :D

 

1/4 chance that you will die when you roll the die. (Okay I will stop)

 

The probability that A, B, or C will walk the plank is 

 

1/4 * 3 or 75%

 

 

Arghhhh!!

 

Hope this helped!!!
