A(b) = 12(b + 9) / 2
12(b + 9) = 2 A(b)
b + 9 = 2 A(b) / 12 = A(b) / 6
b = A(b)
----- - 9
6
B(a) = a
-- - 9
6
It's C
8x + 6=4x + 38
4x = 32
x = 8
<B = 4x + 38 = 4(8) + 38 = 70
Since there are 3 "2's" and 8 total options, the probability is 3/8 or C.
Because b - a could be, for example, b = 5 and a = 7. So if the question were to be 5 - 7 = -2, that would be b - a. If you swap it around, then the question would be 7 - 5 = 2, and that would be a - b. I hope this helps.
