Question

Eight white balls and twenty black balls are in a bag. What is the probability of drawing a black ball in one draw?

Answer 1

Probability is quite simple. In this case, you just need to find the total number of balls (28) and the total number of black balls (20) Now, create a ratio (20/28) Next, simplify it down to 5/7, and that is your answer. I hope that helps! :)

Answer 2

Probability of drawing a black ball in one draw
`= (5)/(7) \\`

Explanation:

The probability of drawing a black ball in one draw

`= (Number of black ball)/(Total number of balls) \\=  (20)/(28) \\= (5)/(7) \\`
