o
5/7

The correct answer is last option

5/7

Step-by-step explanation:

It is given that, eight white balls and twenty black balls are in a bag

To find the probability

From the above data we get,

number of white balls = 8

Number of black balls = 20

total number of balls = 8 + 20 = 28

Probability of getting black ball = number of black ball/Total number of balls

 = 20/28 = 5/7

The correct answer is last option
