The probability is the statistics of your chances of an event occurring which signifies a part of a whole. You express the probability in either fraction form or in percentage. The numerator would be number of all possibilities, while the denominator is the number of all events. In this case, the numerator is the number of white gumballs, while the denominator is the number of all gumballs available.
To solve for the number of white gumballs, you subtract all the other balls to the total.
Number of white balls = 230 - 64 red - 22 blue - 32 orange - 26 green
Number of white balls = 86
Thus,
Probability of white ball = 86/230 = 43/115 or 37%
