Question

A bag contains 8 black marbles, 16 white marbles, 14 red marbles, and 10 green marbles. A marble is drawn at random from the bag.

What is the probability that the marble drawn will not be white?

1/3

2/3

3/4

15/16

Answer 1

The answer is 2/3. It is this because when you add up all the marbles you get 48 then when you simplify 16/48 you get 1/3, finally the opposite of 1/3 is 2/3.
