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?

A.1/3

B.2/3

C.3/4

D.15/16

Answer 1

the probability of a white marble being drawn is 16/48, so to find the probability of it not being drawn subtract 16 from 48.

which would be 32, making the probability of a white marble not being drawn 32/48.

now we simplify the fraction by the gfc which is 16

this leaves us with 2/3 so the answer is B
