Question

a bag contains 27 balls of which some are white and others are red ball is chosen at random the probability of getting a red ball is 2 by 3 find the number of white ball​

Answer 1

Step-by-step explanation:

Let number of red balls be x

P(red ball)=2/3

2/3= x/27

x= 2/3*27

=18

No of white balls = 27-18=9

Answer 2

Answer:

No of white balls=9

Step-by-step explanation:

probability of getting white ball=(1-2/3)=1/3

So no of white ball=(1/3)*27=9balls
