A bag contains 6 green balls and 8 white balls. If two balls are drawn simultaneously, what is the probability that both balls are the same colour?
Choose the most appropriate option:
A) 5/14	B) 8/21	C) 12/21	D) 43/91	E) 47/91
The total number of ways to draw two balls is 14C2 = 91   The number of ways to draw two green balls is 6C2 = 15   The number of ways to draw two white balls is 8C2 = 28   P(two balls of the same colour) = 43/91   The answer is 43/91.
