A box contains 3 blue, 2 white and 4 red marbles. If a marble is drawn at random from the box, what is the probability that it will be a white marble or a blue marble?
If a marble is drawn at random from the box, what is the probability that it will not be a white marble? Total number of marbles = 3+2+4 = 9 . Number of non-white marbles = 3+4 = 7. ∴ P(getting a non- white marble) =79
