Question

in the box there are 24 balls.some of them are blue and other are red.if a ball is taken from the box without looking,the propablity of getting blue ball is 2/3
what is the total nber of blue balls​

Answer 1

Answer:

Total number of blue ball in the box is 16.

Step-by-step explanation:

We have given;

Total no. of balls = 24;

Probability of getting a blue ball or P(blue ball)= 2/3;

Probability of any occurrence or incident is given by;

= Possible no. of chances / Total no. of chances

Hence, P(blue ball) = Total blue ball / total no. of balls

P(blue ball) = Total no. of blue balls / 24;

2/3 = total no. of blue balls / 24;

Total no. of blue balls = 24 * 2/3;

= 8 * 2

= 16

That's all.
