Find the number of ways in which 5 men and 4 women can be seated round a table so that no two women are together.

Parth (parthkohli):

If no two women are together, then we have an alternate sitting pattern: a man, then a woman, a man and so on.

OpenStudy (anonymous):

so there are (5-1)!*4! right?

Parth (parthkohli):

We can't have two men together, right? If we do, then there must be a place where two women are together.

Parth (parthkohli):

I think it is just \(5!4!\)

OpenStudy (anonymous):

Parth (parthkohli):

Ah! Yes.

OpenStudy (anonymous):

Parth (parthkohli):
