Question 572735: A bag contains 2 white marbles, 4 blue marbles, and 6 red marbles. If a marble is drawn from the bag, what is the probability that it is not blue?

2 white marbles + 4 blue marbles + 6 red marbles = total of 12 marbles.

P(not blue) = 8 marbles (2 white + 6 red = 8) are not blue out of 12 total marbles
P(not blue) = 8/12

Reducing by dividing each side by 4 gives ...
P(not blue) = 2/3
