Answer:
5/24 or 20.8%
Step-by-step explanation:
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
If you are asking to simplify, this is what I got. Hope I was able to help
7/8 = 0.875
14/16 = 0.875

Convert the percent into a decimal 25% divided by 100 and do the same for both then add 9$ and all of the other decimals you get
