Question

The probability that a vehicle entering the Luray

Answer 1

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
