11Please read it ,sir.
Can you try and prove that logically instead?
Prove that no of ways in which n identical objects can be dived in r different groups is: n+r-1 C r-1
(I did'nt get the prove of this in any of the books.)

62Try induction.. (The simplest solution :D)
take r=0 then start induction :P
I havent even read the question properly :D
1162oh yeah now i can read it too :)
see you have n 1's
now you have to put some r-1 + signs in between these 1's
so you have the proof?
3it was the same as
no of integral solutions for the eqn x0+x1+x2+.....+xn=r
62Yes sankara. you have recognised that well :)
except that you have replaced r and n?
1msp do you not recognize the proof bhaiyya has in mind ..
or was it simply that you are giving another method ..
3dude dat was by induction,i am searching for a combinatorial proof.Also i donno abt induction,
1nishant sir,plz give d induction proof....m not getting it....
