A quesiton....that sounds like its my homework

[magomago]

I have three elements. How do I calculate the

What is the number of combinations of 3 objects taken 3 at a time....except that the objects repeated (IE: 122 is valid, so is 111).

If anyone cares, NO this isn't HW


The new DOTA beta has the invoker again and we are trying to figure out the mathematical symbolism that would express this. We can brute force this on our own by just listing all possiblities and then counting them (and then we can find the number of ults - which are 10). But we are trying to figure out how to figure out how many ways to express symbolically.

Little Help here?

And yes...instead of doing HW we are getting frustrated with this =)

The math you need is called combinatorics. This link will show you how to count all 4 kinds of countings:

The answer you seek

Need to buff alchemist.

3^3 = 27

That class was a bitch!

Combination with repeats gave the right formula.

well usually what I do is go Luna and just pwn everyone cause I'm overpowered.. only in -arem games though.

piimp it was combinatorics. invoker ftw


and yes....they need to CAREFULLY buff alchy lest he just gets too crazy....and take on 5 men at once xD

Luna - you too squishy disabler +any dps will pwn you the fastest. Of course this assumes you have team work...which is never the case in pubs

Yeah, too bad no more radiance before lvl 12 =)

No kidding. A 29/200 on the final was a C in my combinatorial mathematics class! I still have the class pdf if anyone wants to torture themselves.
