@RAKESH RAUSHAN-You are right,can be solved as
Probability of hitting at least two means probability of hitting any two* one miss+ probability of hitting all.
e.g (A hit*B hit*C miss)+(B hit*C hit*A miss)+(C hit*A hit*B miss) + (A hit*B hit*C hit)
= 3/6*4/6*4/6+3/6*2/6*2/6+3/6*2/6*4/6+3/6*2/6*4/6
=1/2

ans is--1/2.
probability that they will hit the terget is 3/6, 2/6 , 4/6 respictevely and that of not hitting is 3/6, 4/6 and 2/6 respictevely
so probability of hitting at least two target will be ...............
3/6*4/6*4/6+3/6*2/6*2/6+3/6*2/6*4/6+3/6*2/6*4/6=1/2 ans
