Official Solution:
A certain bag contains 60 balls — 22 white, 18 green, 11 yellow, 5 red, and 4 purple. If a ball is to be chosen at random, what is the probability that the ball will be neither red nor purple?
A. 0.09
B. 0.15
C. 0.54
D. 0.85
E. 0.91
According to the stem, the ball can be white, green, or yellow, so the probability is \(\frac{white + green + yellow}{total} = \frac{22 + 18 + 11}{60} = \frac{51}{60} = 0.85\).
Answer: D
