• If c < 0 then a shift down of c units
Here the shift is 1 unit up, thus
y = | x | + 1
a) The total number of vehicles is 2450, and the number of vehicles that didn't use a toll pass is 1566, so the probability is:

b) If it's given that the vehicle is a truck, the number of trucks is 951, and the number of trucks that didn't use a toll pass is 610, so the probability is:
