Aband leader randomly selects 2 students out of 75 band members. if you and your brother are both band members, what is the probability that you are both selected?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
