Six girls and four boys have entered the science fair. first, second, and third place awards are to be given out. what is the probability that exactly one girl and two boys will recite awards? express your answer as a percent

Given:

6 girls

4 boys

Probability of 1 girl being chosen: 1/6

Probability of 1 boy being chosen: 1/4

Probability of another boy being chosen: 1/3

1/6 = 0.17 x 100% = 17%

1/4 = 0.25 x 100% = 25%

1/3 = 0.33 x 100% = 33%

17% + 25% + 33% = 75%

The probability that exactly one girl and two boys will receive awards is 75%.
