umbers appearing on​

Answer 1

Step-by-step explanation:

a bag containing 5 red balls and blue balls

the number of blue balls is not mentioned

since the probability of drawing a blue ball is thrice the red balls,

blue balls are 15

probability of blue balls=no of red ball

no of blue balls

or,5 1

15 = 3

and no of blue ball is 5*3=15
