∆ The probability sum of two balls is 1.
∆ Therefore 2/3+ probability of finding blue balls = 1.
∆ Then probability of finding blue balls is 1-2/3
1/3.
∆ no.of balls is 1/3 × 24
∆ Then no.of balls is 8.
∆ I think so my answer is correct.

gellisurabhi: Isn't my answer correct sir
gellisurabhi: Siddhartha rao sir
RinaPoddar: answer given is 8
gellisurabhi: there is no opitin of 1/3
gellisurabhi: now see answer
gellisurabhi: i didn't see in the question that they had asked no.of balls
gellisurabhi: I though only probability of finding balls

Given that number of blue balls + red balls = 24.

Given that probability of drawing a red ball = 2/3.

Then probability of drawing a blue ball = 1 - 2/3 = 1/3

Then,

Number of blue balls = (1/3) * 24

= > 24/3

= > 8.


Therefore, the number of blue balls = 8.


Hope this helps!
