Is there any online combinations calculator that can do the following:
Compute how many ways I can select e.g. 4 items out of a bunch of e.g. 19 items where some of these 19 items are repeated. Example of this:
If I have 2A's, 4B's, 4C's, 3D's, 5E's & 1F (A,A,A,B,B,B,B,C,C,C,C,D,D,D,E,E,E,E,E,F). How many combinations of 4 letters from this list is possible?
I'd love if there's such a calculator that can not only give me the final numerical answer but shows me the steps AND/OR a listing of all possible combinations e.g. ABCD, BCDE,...etc
I found this: http://webviewworks.com/cgi-bin/math/pe ... r_word.cgi
and it's close to what I wanted but it doesn't show me the steps nor does it show a complete listing. If there's another tool that can show the steps AND/OR a listing of the different combinations, then please let me know...
