(Out comes here means the possible sector where the pointer stops)

A spinner has four colours as shown in the figure. When we spin it once, find a) At which colour, is the pointer more likely to stop? b) At which colour, is the pointer less likely to stop? c) At which colours, is the pointer equally likely to stop? d) What is the chance the pointer will stop on white? e) Is there any colour at which the pointer certainly stops?

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 transport are respectively (3)/(10),(1)/(5),(1)/(10) and (2)/(5) . The probabilities that he will be late are (1)/(4),(1)/(3) and (1)/(12) , is he comes by train, bus and scooter respectively, but if he comes by other means of transport, then he willnot be late. When he arrives, he is late. The the probability that he comes by train is
