I assume that there only eight seats. So there only $\displaystyle 8$ ways to seat the couple opposite each other. WHY?

There are then $\displaystyle 3\cdot 2$ ways to seat*the other two people*on the sunny side. Can you explain that?

How many seats remain and how many ways can they be occupied? - Jan 8th 2013, 07:46 PMarshad2468Re: permutation and combination
