Probability that a vehicle entering the Luray Caverns has Canadian license plates = 0.12

Probability that it is a camper = 0.28

Probability that it is a camper with Canadian license plates = 0.09

a. Probability that a camper entering the Luray Caverns has Canadian

license plates = 0.09

b. Probability that a vehicle with Canadian

license plates entering the Luray Caverns is a camper = 0.09/0.12

= 0.75

c. Probability that a vehicle entering the Luray Caverns

does not have Canadian plates or is not a camper = 0.88 + 0.72 - 0.81

= 0.80
