Question 39272
I get 10/64 or 5/32 for an answer.
The combinations of die numbers that ass up to greater than 36 are:
die 1: 7
die 2: 6 or 7 or 8
-----------------------
die 1: 8
die 2: 5 or 6 or 7 or 8 
------------------------
die 1: 6
die 2: 7 or 8
-----------------------
die 1: 5
die 2: 8
-----------------------
That covers all the possibilities
Now add them up. Whenever you want the probability, P of a OR b,
P = a + b.
There are 10 ways to get side 1 + side 2 greater than 36
