A bag contains lottery balls that are numbered 1 throught 15. If you draw two numbers without replacement, what is the probability that you will draw two even numbers?
-----
There are 8 "even" balls.
# of ways to succeed: 8C2 = 28
# of ways to draw a pair randomly: 15C2 = 105
---
P(draw 2 even) = 28/105
