# A Ball is Drawn at Random from a Box Containing 12 White, 16 Red and 20 Green Balls. Determine the Probability that the Ball Drawn Is: White - Mathematics

A ball is drawn at random from a box containing 12 white, 16 red and 20 green balls. Determine the probability that the ball drawn is:

white

#### Solution

Total number of balls in the box =48

Total possible outcomes on drawing a ball=48/

n(s)=48

Event of drawing a white ball =E=12

n(E)=12

Probability of drawing a white ball=(n(E))/(n(s))=12/48=1/4
