In a swimming race $3$ swimmers compete . The probability of $A$ and $B$ winning is same and twice that of $C$.What is the probability that $B$ or $C$ wins. Assuming no two finish the race at the same time.

Q. In a swimming race 3 swimmers compete . The probability of A and B wining is same and twice that of C. What is the probability that B or C wins. Assuming no two finish the race at the same time.

Q. Three athletes A, B and C participate in a race. Both A and B have the same probability of winning the race and each is twice as likely to win as C. The probability that B or C wins the race is

Q. 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 (Assume no dead heat)

Q. 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" is $p$ and the probability that $a,b,c$ each wins one race is $q$, then the value of $\frac{p}{q}$ is (Assume no dead heat)

Q. $A$, $B$, $C$ are three horses in a race. The probability of $A$ to win the race is twice that of $B$ and probability of $B$ is twice that of $C$. What are the probabilities of $A$, $B$ and $C$ to win the race?
