>>12722430Thanks but what Im trying to understand is the mn rule, permutations, this definition:
>An ordered arrangement of distinct objects is called a permutation. The num-ber of ways of ordering n distinct objects taken r at a time will be designated
by the symbol P (n r)
and Combinations
I tired to understand the Haruhi problem that /sci/ solved solve in the hopes of understanding how these probabilities are calculated.
Your formula you posted, idk how to latex but k is groups and n is the total amount of elements in the set correct? So what the formula describes is the number of ways the different elements can be arranged correct? This is a permutation?
Is a combination just the inverse where the order matters?
