actually skip was right.
it's 22x21x20x19x...x2x1 = 1124000727777607680000
:toothless |
Haha, he could use the same track more than one time couldnt he? ;)
Ok, I admit.. forgot that :p
Alphabetically sounds like a great idea! Would be cool to do with a good tracklist tho :p

Dude, relax? :) I know how permutations work :) |

Take a scientific calculator. Enter the number of tunes (22) and press "!" after it. The answer is the total number of possible combinations, assuming that none of the set of 22 are the same. There's a formula for how the "!" key works, but I can't (nor need to) remember it.
1.12x10^21 is the right answer. |
So skip and myself were right
22! (or 22 nPr 22) do the trick on my Texas Instruments-83
Be aware that 22! is the same as calculating 22x21x20x19x...x2x1, for the not-so-geniuses, only difference being that the scientific calc gives 1.12x10^21 as an answer for 22!, and 1124000727777607680000 for 22x21x20x19x...x2x1. |

It gave me a much more accurate answer. I just couldn't be arsed to write it. |

Yeah got it too on the TI-83 here, thought I'd stick to the 1.12x10^21 too, keeping it easy
1.124000728x10^21, I'd probably have to make it 1.12 or 1.124 on a math test anyway, getting used to rounding it off

those are for n00bs. mathcad is what true men use! ;)

i think it's ok, but it's the tiest proper TI there is, so i doesn't have nearly all the functions i'd want. anyway far better than casio or some other crap calculator! :D |

I didn't ask for how many possibilities exist to create a tracklist but thanks anyway.
:rolleyes:
Despite making fun of me there might be still somebody out of all those TAs that can give me a good suggestion for a tracklist. |
