An insurance company insured 2000 scooter drivers, 4000 car drivers and 6000

truck drivers. The probability of an accidents are 0.01, 0.03 and 0.15 respectively.

One of the insured persons meets with an accident. What is the probability that

he is a scooter driver?

 

ans)  p(scooter)=1/6  p(tr)=1/2  p(car)=1/3

therefore required probability =                1/6 x .01

                                              ----------------------------------

                                              1/6x.01 +1/2 x .15   +1/3x.03
