Given a set of numbers {5,6,7,8,9,10}, what is the probability that is two numbers are selected randomly that their sum will be greater than 12?  Pick one:
A) 13/15
B) 9/12
C) 13/12
D) 13/11
E) 13/16
First problem is 6C2 = 12 .. Not 20..   Point 2, your sum should be greater than 12, so these are the following possibilities you have   ({5,8},{5,9},{5,10},{6,7},{6,8},{6,9},{6,10},{7,8},{7,9},{7,10},{8,9},{8,10},{9,10}) which leads to 13 pairs   So the probability is 13 on 12 or 13/12..   ANSWER:13/12
