Question 467098: a pair of dice are rolled. what is the probability that a sum of five is rolled given that only one of the dice shows a three. Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! There are possible outcomes.
The outcomes where one of the dice is 3 are
(3,2) and (2,3)
a total of 2 elements.
Hence the desired probability is 2/36, or 1/18.
