Question

A pencil holder contains only six blue pencils and three red pencils. If two pencils are drawn at random, what is the probability both are blue?

Answer 1

6 blue pencils and 3 red pencils means 9 total pencils. So the probability of pulling out ONE blue pencil would be 6/9 or about 67 percent. TWO blue pencils would be HALF of that. So 6/9 * 1/2 which is 6/18 or 1/3 or about 33 percent.
