Two buses A and B are scheduled to arrive at a town central bus station at noon. The probus A will be late is `1/5`. The probability that bus B will be late is `7/25`. The probability that the bus B is late given that bus A is late is `9/10`. Then the probabilities:

Two buses A and B are scheduled to arrive at a town central bus station at noon. The probability A will be late is 1/5 . The probability that bus B will be late is 7/25 . The probability that the bus B is late given that bus A is late is 9/10 . Then the probabilities: (a) probability that neither bus will be late on a particular date is 7/10 (b) probability that bus A is late given that bus B is late is 9/14

A doctor is to visit a patient. From the past experience, it is known that the probabilities that he will come by train, bus , scooter or by other means of transportation are respectiely 3/10,1/5,1/10 or 2/5 . The probabilities that he will be late are 1/4,1/3 and 1/12 if he comes by train, bus and scooter respectively but if he comes by other means of transport, then he will not be late. If the arrives late, find the probability that he comes by train.

A candidate has to reach the examination centre in time. Probability of him going by bus or scooter by other means of transport are 3/10, 1/10, 3/5 respectively. The probability that he will be late is 1/4 and 1/3 respectively, if he travels by bus or scooter. But he reaches in time if he uses any other mode of transport. He reached late at the centre. Find the probability that he travelled by bus
