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

Step-by-step explanation: 2/3

The probability that it will not be white is the same as 1 - probability that it is white. That is

P (not w) = 1 - P (w)

P (w) = number of white / total number

P (w) = 16/48

P (w) = 1/3

Therefore:

P (not w) = 1 - 1/3

P (not w) = 2/3

Therefore, the probability that the marble drawn will not be white = 2/3

Total marbles: 8 + 16 + 14 + 10 = 48

Marbles that are not white: 48 - 16 = 32

Probability it will not be white: 32/48 = 2/3
