Calculate the probability that the total benefit paid to the family does not exceed 5.
They have a graph 0<x<10 and 0<y<10 with the line x+y=8. how did they get x+y=8?

There's already threads on this so you'd probably help yourself but searching. The quick answer is if there is a deductible of 1 and 2 so we want the benfiit paid to not exceed 5, they are already going to pay 1 and 2 for deductible so 1 + 2 + 5 = 8
