If two different numbers are randomly selected from set { 1, 2, 3, 4, 5} what is the probability that the sum of the two numbers is greater than 4?  Pick one:
A) 2/5 B) 3/5 C) 4/5 D) 6/5 E) 7/5
First problem is 5C2 = 10 .. Not 20..   Point 2, you sum should be greater than 4, so these are the following possibilities you have   ({1,4},{1,5},{2,3},{2,4},{2,5},{3,4},{3,5},{4,5}) which leads to 8 pairs   So the probability is 8 on 10 or 4/5..   ANSWER:4/5
