Like Ground-Fire,Water-Grass,Steel-Ground,etc.
I would like to know an estimate of all possible types in figures(numbers),even ones that do not currently exist(eg. Fire-Water), and if there are any Pokemon in that particular typing(as in Dark-Flying = Honchkrow/Murkrow).
All 17 types should be counted,and Ghost-Dark and Dark-Ghost ARE THE SAME(but if you choose to write both,well and good;It may be more time-consuming,but easier)
Thank You all those who contributed! Your work is deeply appreciated!
P.S. I am almost sure that this wasn't asked before,but if it was please leave a comment.
It's a combination. Order does not matter, and each item can only be used once.
n=17 (total types) r=2 (number possible)
T=n!/(n-r)!(r!)
T=17!/(15)!(2)!
T=(17 16)/(21)
T=272/2
T=136 Totals types.
This number only gives for dual-typed pokemon, so you would add in 17 for every pure type pokemon, making a grand total of 153 possible types.
