Apair of dice is rolled. find the probabilities of the given events. the sum is 6, given that the sum is less than 8.

So there are 36 possible combinations with a pair of dice. the amount that add up to 6 is 5. 5/36=0.138888888888888(repeating) which to put in a percent is 13.9%. so the probability that the sum is 6 would be 13.9%.
but if the sum is already known to be less than 8 then that means there is only 21 possible rolls, so we would have 5/21 instead of 5/36. 5/21=0.238095(repeating) which to put as a percent is 23.8%
so the probability the sum will be 6 given that the sum is less than 8 is 23.8%
Hope this helps.
