I have 3 questions on my homework that i am having trouble with and I need help quickly. Here they are.

From a group of 12 people I am to form 4 teams of 3 players each. In how many ways can this be done. Note that they are not ordered.

From a group of 6 men and 7 women, 4 men and 4 women are to be seated around a circular table, alternating men and women. We are to determine only who sits next to whom, not the particular seats they will take. How many possible choices do we have?

How many paths are there along the edges of a cube that visit each vertex exactly once?

you can leave a post or aim me at LifeInIstanbul with help thanks again everyone.

(<SUB>12</SUB>C<SUB>3</SUB>)(<SUB>9</SUB>C<SUB>3</SUB>)(<SUB>6</SUB>C<SUB>3</SUB>)(<SUB>3</SUB>C<SUB>3</SUB>)/(4!).
<SUB>n</SUB>C<SUB>k</SUB> is the combination of n taken k.

How many ways can you choose the women?
How many ways can you choose the men?
You can seat the women in every other seat in [(4-1)!] ways. Why (4-1)! ?
Once the table has a person seated it is organized. How many ways can you now seat the men?
 
These are the exact questions i was given(cut/paste from internet site) use logic you can figure it out i have the answers if u have a guess i will let you know if u got it right.
 
The tutor wasn't asking you for the answers; he was trying to help you understand the reasoning and steps in working your way toward those answers.

Unrequited, As MS Eliz said I was simply giving you directions for understanding.
I have worked in this area for years, so I indeed know the answers.
If you also have the answers, then now your job is the understand how they were gotten.
