Question

jungkook draws a ball from a bag that contains white and yellow balls the probability of choosing a white ball is 2 by 9 if the total number of ball in the bag is 36, find the number of yellow balls​

Answer 1

Let the probability of yellow balls be x.

Total balls=36

Probability (White Balls)=2/9

Therefore,2/9+x=1

By calculating,

The value of x=7/9

Let number of yellow balls be y.

7/9=y/36

By evaluating,

We get y=28.

Hence,The number of yellow ball is 28
