Question 740156: You roll a pair of dice 24 times. What is the probability of seeing at least one total that is 11?
I know there are 36^24 possible outcomes, there are only two ways to get 11 and one to get anything higher than that so would the numerator be 3?
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! probability of getting 11 with both dice is 2/36
since there are 36 ways dice can be rolled i.e (1,2),(1,3).....(6,6)
and there are two ways 11 comes up, hence p = 2/36
now this implies there is (34/36) probability that 11 will not come up
and
(34/36)**24 probability that 11 will never show when the dice are rolled
24 times.
then
1- (34/36)**24 probability that 11 will appear at least once
