A person goes to office either by car, scooter, bus or train probability of which being`1/7, 3/7, 2/7 and 1/7` respectively. Probability that he reaches office late, if he takes car, scooter, bus or train is `2/9, 1/9, 4/9 and 1/9` respectively. Given that he reached office in time, then what is the probability that he travelled by a car?

A person goes to the office either by a car, or scooter, or bus, the probability of which being (2)/(7),(3)/(7),(2)/(7) respectively. The probability that he reaches office late if he takes a car, or scooter, or bus is (2)/(9),(1)/(9),(4)/(9) respectively. If he reaches office in time, the probability that he travelled by car is k, then the value of 24k+7 is equal to

A person goes to his office by using different means of transport on different days. It is know that the probabilities that he will come by train, bus, scooter or by car are respectively 1/10, 3/10, 2/10 " and " 4/10 . The probabilities that he will be late are 1/4, 1/5, 1/6, " and " 1/3 if he comes by train, bus, scooter and car respectively, on one day when he reaches office, he is late. What is the probability he has come by train?

A cadiadate has to reach the examination centre in time, Probality of him going by bus or scooter or by other means of transport are (3)/(10),(1)/(10) ,(3)/(5) respectively. The probability of getting late , if the travels by bus is 1/4 ,1/3 if he travells by scooter and 0 for any other medium. But he reaches in time if the uses any mode of transport . He reached late at the centre. The probability that he travelled by bus is -

The probabilities that a Man Makes a journey by car, Motor cycle or on foot are (1)/(2),(1)/(6),(1)/(3) respectively. The probabilities of an accident when he uses these means of transport are (1)/(5),(2)/(5) and (1)/(10) respectively. If he met an accident then the probability that he is travelling on foot is

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.

The probability that a student passes in mathematics is 4/9 and that he passes in physics is 2/5. Assuming that passing in mathematics and physics are independent of each other, what is the probability that he passes in mathematics but fails in physics?
