Question

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

Answer 1

Answer:

5/6

1/3

Step-by-step explanation:

Let say number of Red Balls = R

Number of White Balls = 2R

Number of Blue Balls = 3R

Total Balls = R + 2R + 3R = 6R

6R = 24

=> R = 4

Red Balls = 4

White Balls = 8

Blue Balls = 12

Probability of ball not red  =  1  -  (red balls/total Balls)  =  1 - 4/24

= 1 - 1/6

= 5/6

Probability of White = White Balls/Total Balls  = 8/24 = 1/3
