let A - randomly selected person is US citizen = 200
B- randomly selected person is canadian = 200
C-Person Fueling due to good price= 205
D-Person fueling due to other reasons= 195
18) Probability that selected person is fueling due to good price= 205/ 400 = 0.5125 = 0.513(A)
19) Probability that selected person is US citizen and fueling due to other reason = 125/400 = 0.3125 =0.313 (D)
20) Given that they are fueling with other resons(n=195) probability that they are US citizen
