Question

24 balls are in a bag.some are white and remaining black the probability of drawing a white ball is twice that of drawing a black ball find the number of white balls

Answer 1

Answer:

number of white balls = 16

number of black balls = 8

Step-by-step explanation:

let the no. of black balls be x

white balls=2*x

                =2x

therefore,

2x+x=24

3x=24

x=24/3

x=8

white balls =2x

                  =2*8

                  =16
