Question

The game of backgammon uses two standard dice, each with the numbers one through six. You need to roll double 5's to win the game. What is the probability you will get that result on your next roll?

Answer 1

-- Each cube can land in 6 different ways.
-- The probability that the first cube will show a 5 is 1/6 .
-- The probability that the second cube will show a 5 is 1/6 .

-- The probability that they BOTH will show a 5 is

(1/6) x (1/6) =

1/36 = 2.8 percent (rounded)
