Whenever horses a , b , c race together...

Whenever horses `a , b , c` race together, their respective probabilities of winning the race are 0.3, 0.5, and 0.2 respectively. If they race three times, the probability that the same horse wins all the three races, and the probability that `a , b ,c` each wins one race are, respectively. a.`8//50 ,9//50` b. `16//100 ,3//100` c. `12//50 , 15//50` d. `10//50 ,8//50`
