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 -
