Discrete Maths, Lecture-12 : Counting-II

These are my notes from 12th lecture of discrete mathematics course taught at Arsdigita university by Shai Simonson. Other posts relating to this are here.

This lecture covers generalized permutation and combinations (that basically means repetition is allowed). Though there are "formulae" presented for each case but more emphasis is(and should be) given to how we can think and solve the problems of generalized permutation and combinations using the already covered 5 principles and simple permutation/combination. The intention of this lecture is not to give you the formula but to teach you how you reach to them.

Here are my notes...
