E. 80

Okay, so the possibility of m and n are like this:

m = 200 and n =1

m = 100 and n = 2

m = 50 and n = 4

m = 40 and n = 5

m = 25 and n = 8

m = 20 and n = 10

Do I need to count their probability one by one then adding them up to make \(\displaystyle \frac{40}{87}\)? Or am I not supposed to do that?
