Question

In how many ways can four married couple attending a concert be seated in a row of eight seats if the members of each sex are seated together?

Answer 1

So there are two ways, the guys on the left, ladies on the right, or vice versa.

Answer 2

I guess there are more ways, I wasn't paying attention!
For each of the two ways, the guys have 4! ways among them, same for the ladies.
So there are 2*4!4!=1152 ways.
