Question

A bag contains 5 red, 8 green and 7 blue balls. One ball is drawn at random. What is the

probability that ball drawn is non-red?​

Answer 1

Answer:

3/4

Step-by-step explanation:

Red balls = 5

Green balls = 8

Blue balls = 7

Sum of balls = 20

Balls which are not red = 8 + 7

= 15

Hence, probability of getting a non-red ball = 15/20

= 3/4
