In an inventory of some experimental automaker, 66% of vehicles are cargo vans and 34% of vehicles are crossovers. Suppose that 73% of cargo vans they have run on LPG and 55% of crossovers they have run on diesel. Assume that they only have vehicles running on either LPG and diesel. (a) Find the probability that a randomly selected vehicle from the inventory is a crossover running on LPG. Round your answer to four decimal places. (b) If you randomly select one vehicle that runs on LPG from that inventory, what is the probability that it is a cargo van? Round your answer to four decimal places. (c) If you randomly select nine (9) vehicles from that inventory, what is the probability that none of them are crossover running on LPG? Assume each vehicle is selected independently from each other with equal probability. Round your answer to four decimal places. Hint: Your answer in (a) could be useful.
