If 6 men and 6 women are to be seated about a round table and take their seats randomly, determine the probability that a particular woman is not seated next to either of the 2 particular men.

Thanks

Hi, How would I determine the number of ways, instead of Probability?

Thanks again

Total arrangements of 12 people around a circular table = 11!.

Arrangements with your condition = 11! x 36/55 = 26127360.

Perhaps I wasn't clear enough =\

I was wondering how I could do this by first determining the number of ways... (ie. without determining the probability). I think there's a way, but not I'm not sure how to work it out...

Thanks

Thanks for that. Would it be possible to do it using nCr?
