Question

If two fair dice are? rolled, find the probability that the sum of the dice is 9?, given that the sum is greater than 3.

Answer 1

need to find all the probabilities

rolling a 2 = 1/36

3 = 2/36

4 = 3/36 etc.

rolling a 9 =4/36

total of rolling anything greater than 3 = 33/36 then divide

4/36 / 33/36 = 4/33 probablility
