Answer:
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!
