Amath class had 5 girls and 5 boys in the seventh grade and 1 girl and 7 boys in the eight grade. the teacher randomly selects a seventh grader and an eight grader from the class for a competition. what is the probability that the students she select are both boys?

Step-by-step explanation:

5 girls and 5 boys in the seventh grade and 1 girl and 7 boys in the eight grade

Total number of 7th grade = 10

Prob(boy 7th grade) = 5/10 = 1/2

Total number of 8th grade = 8

Prob(boy 8th grade) = 7/8

Prob(boy 7th and boy 8th) = 1/2×7/8

= 7/16

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
