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
white 5 61 680
green 9 74 713
red 1 15 107

Just take the result with the lowest error (more trials - less error)(You can plus the results for the lowest error)  and divide it by the total amount of trials.
