A game at a county fair has a spinning drum holding 15 colored plastic balls: some white, some green, and some red. Every time the drum spins, one ball drops out, its color is recorded, and then the ball is placed back in the drum. The table shows the results after 15, 150, and 1500 spins.
What is the best estimate of the number of white balls in the drum?
Outcome Number of trials
15 150 1500
