thanks Ron, i got it
But i have a small doubt here,
why arent we considering the total possible arrangements here,
i.e total no of ways why are we not taking as 10!
And favorable cases why not,
6*2* 3! * 5!.
Please explain this that why are we not taking other persons as well. why are we just taking A & B in the total number and favorable cases...???
