some body please clear this discrepancy
from 6 if we choose 3 , how do we denote it , all books and materials show this as 6C3
but here parrot man shows this as 6c3 and moderator shows this as 3c6 , leading me to becoming confused !!
according to me , the larger one goes at the top and the smaller sub group goes below
so from 6 if we choose 3 then 6C3.
so please if someone could confirm why is 3C6 denoted here , and does 3C6 mean the same as 6C3 ? are they same ?
so from n if if have to choose , 3 or 4 or 5 etc shouldn't it be nc3 , nc4 , nc5 etc .... Please clear my confusion
