# 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: Red Or 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:

red or white

#### Solution

Total number of balls in the box=48

Total possible outcomes on drawing g ball=48

n(s)=48

red or a white ball =12+16=28 balls

Event of drrawing a red or white ball=E=28

n(E)=28

Probability of not drawing a green ball= (n(E))/(n(s))=28/488=7/12
