Answer 2

Calculating the Percentage of Black Balls

To calculate the percentage of black balls in the given set, we can use the following formula:

Percentage of black balls = (Number of black balls / Total number of balls) x 100

Given: - Number of black balls = 12 - Number of green balls = 8 - Total number of balls = 12 (black) + 8 (green) = 20

Using the formula: Percentage of black balls = (12 / 20) x 100 = 60%

So, the black balls make up 60% of the total number of balls in the set.
