Question

A box contains 96 red marbles, 55 white marbles, and 11 blue marbles. If a marble is randomly selected from the box, what is the probability that it is not white? Express your answer as a simplified fraction or a decimal rounded to four decimal places.

Answer 1

P = 0.6605

Explanation:

A box contains 96 red marbles, 55 white marbles, and 11 blue marbles

=> The total number of marbles N = 96 + 55 + 11 = 162

=> The number of marbles that are not while: N = 96 + 11 = 107

=> The probability that a marble randomly selected from the box, is not white:

P = number of elements/total number of elements = 107/162 = 0.6605

Hope this helps!
