In a shooting competition, the probability of hitting the target by P is 3/5. By Q is 1/3 and by R is 2/5. If all they fire independently at the same target calculate the probability that only one of them will hit the target.

Let us assume the events "P hits the target", "Q hits the target" and "R hits the target" are independent.
as P(P doesn't hits the target)=1-3/5⇒2/5
P(Q dosen't hits the target)=1-1/3⇒2/3
P(R doesn't hits the target)=1-2/5⇒3/5
P(that no one will hit the target)=2/5×2/3×3/5⇒12/25
P(that atleast one of them hit)=1-12/25⇒13/25
:)Hope this ans would help u...
