Question

a bag contains 24 balls of which the number of blue ball is thrice the number of that was and the number of white balls is twice the number of that was a ball is selected at random what is the probability of not red white​

Answer 1

blue balls=3x

white balls=x

total balls=24

3x+x=24

x=6

blue balls=3*6=18

white balls=6

1. Prob of not getting red ball = 24/24=1

1. Prob of not getting white ball = Prob of getting blue ball = 18/24=3/4 = 75%
