Formulae for combination with repetition for choosing 5 balls out of 10 with replacement.
In last question formulae for combination with repetition is given as (n+p-1)/p however the document/material attached showed formlae for combination with repetition is (n+p-1)!/((n-1)!*p!).
I'm confused to understand which one is correct. Please clarify.

Hey Vipin,
Thank you for the question and apologies for the late reply!
A similar question has been recently resolved here. We will update the lecture notes as soon as possible to contain the definition of the 'n-choose-k' notation.
Kind regards,
