Mathematical Sciencey Help? Kind of simple.

So in Math, we're learning how to calculate how many outcomes there can be from a certain number of letters/choices.

So my Math teacher assigned me this:
To list all possible combinations for the word GOOGGOG.

Like GGGGOOO, OOOGGGG, OGOGOGG. Get it? There are 35 combinations. I've only got around 20.

Can somebody help me find them all? 😊

@trish

... I thought there were 5040. Permutations. If you used every letter. It would be 7!, right?

trish • 8 May 2013 at 1:51 AM

@jix Yes but this one is made of 2 letters. You're right if the letters in the 7-letter word were all different, resulting in 5040 combos, but this is only 2.

@trish

Oh yea. Okay, lemme look over this. XD

Have ya tried Google-ing it?

trish • 8 May 2013 at 2:01 AM

@jix Hmm idk what to google. 😋 My teacher said it was 35 combos, but shouldn't it be 42? (7x6) right?

jix • 8 May 2013 at 2:06 AM

@trish

Yea, I though so too. XD

Try "permutations of 2 letters in 7 letter word". XD

trish • 8 May 2013 at 2:07 AM

@jix But I'm actually looking for the combinations. ._.

jix • 8 May 2013 at 2:07 AM

@trish

... aren't they the same? Then look up combinations. XD

trish • 8 May 2013 at 2:10 AM

@jix asdfghjkl;' aint nobody got time for dat. I'll just beat my tablemate silly until he hands over the combos. ;-;

jix • 8 May 2013 at 2:20 AM

@trish

XD Okay. Good luck.

Oh, and I just realized that the draft I'm making isn't due until May 29th, so I was rushing for no reason. XD
