Answer 1

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
