TJD, TAD, TCD, TJM, TAM, TCM, TJG, TAG, TCG,

now the other row! When you've got all possibilities, cross out the ones that are repeated, so you've only got one. Easy!

This is a combinations questions you can solve it with multiplication to determine the number of possible answer then you will now how many to list. So it's 3*3*3 that's 27. Then work methodically down the list of names.

TJD

TJM

And so on...

Best of luck.

Stop cheating.

You're pathetic.

Do your own work.

If you can't solve it on your own, study more. If studying doesn't help, get a tutor. If that doesn't help, you better learn to dig ditches or dance on a pole because you're too stupid for the class.

Stop trying to take the easy way through life!

How in the hell is that physics?!

Jesus...

Put them into columns (TJD, SAM, BCG) then mix and match!

I'm not doing it for you; that's downright lazy!
