Question

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

Answer 1

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%.

Answer 2

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

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that there are:-

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%

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