Hi
First u need to select 8 chocolates out of nine and distribute one to each (Since each has to get atleast 1) This can be done in 9C8 x 8! ways
Now the remaing 1 chocolate can be given to any one student i.e 8choices So total ways will be 9x9C8x8! ways.

Hi,
Thanks for the reply. But the answer given is different, it says 36 * 8! is the correct answer. Please let me know how to get to that. Thanks
