10:17, sir what happens when we have n as odd numbers of particle..then maximum probability State be?

[@abhishekmanna5002]

There will be then two most equally probable one when r=(n+1)/2 and when r=(n+3)/2.

[@shishirjha7744]

Excellent. You may ignore Sreling approx. It is very simple & does not need any conceptual funda.

[@ro-chitasingh5887]

How do we tell the most probable state for lets say odd no of particles? Since, n/2 in that case won't be discrete. So, would it be (2n-1)/ 2 then?

Sir i am not your student. But sir you are doing nice job. Tomorrow i have exam of stat mech. And still i did not studied anything. I hope your lecture will help me in my exam. Thank you so much sir😇😇👍👍
