So, we have 3 types of items (a,b,c)
in a collection and the number of items available is unlimited.
If every time we choose 3
random items from the above collection.
What is the number of possible distinct
outcomes - if we are not interested in the order of the items that we are pulling out of the collection
e.g. aab
is the same as pulling baa
or aba
.
Also what is a general aproach for n
item types?
Thanks.
