Question

Total number of balls 24 .Blue balls 3 times red , white balls 2 time red . Find the probability not getting red ball

Answer 1

Answer:

blue ball = 3x

white ball = 2x

red ball = x

now,

3x + 2x + x = 24

6x = 24

x = 4

blue ball = 3 * 4 = 12

white ball = 2 * 4 = 8

red ball = 4

so ,

the probability of not getting red ball = number of outcomes event / total events

= 4 / 24

= 1/ 6

hence , the probability of not getting red ball = 1 / 6

hope it helps you
