This is the original question:
In a shooting competition, probability of A hitting target is 2/5, by B is 2/3 and C is 3/5. If all of them fire independently, what is the probability that only one will hit target?
A) 4/25
B) 1/3
C) 3/25
4) 2/3
Answer:
Probability of A hitting target is 2/5, by B is 2/3 and C is 3/5
a: 2/5 * 1/3 * 2/5 = 4/75
b: 3/5 * 2/3 * 2/5 = 12/75
c: 3/5 * 1/3 * 3/5 = 9/75
-------------------------------
a+b+c=25/75=1/3
