Bob can go to work by one of four modes of transportation: 1.) bicycle, 2.) car, 3.) bus and 4.) train. If he takes his bicycle, Bob has a 10% chance of getting to work late. Because of heavy traffic, there is a 48% chance of being late if he takes his car. If he goes by bus, which has special reserve lanes to help keep schedule, but can be over crowded forcing him to wait for the next bus, he has a 12% chance of being late. The train runs on a very specific schedule, so he is on-time 95% of the time when he decides to take the train. Bob's cube mate knows that Bob rides his bike 60% of the time. When the cube mate sees Bob come in late to an early morning meeting, the cube mate begins to calculate the likelihood that Bob took various modes of transportation. Match the correct value with the probability questions Bob's cube mate had below:
