I am not sure how to begin this one. Total outcomes would be 11!, so i was assuming with Mr and Mrs A sitting opposite 10!, but I think that is just them sitting apart. You will see what I mean.

Two couples (Mr&Mrs Band Mr&Mrs B)and 8 other people are to be

randomly seated at a round table. In how many of the possible 11! circular

arrangements will Mr and Mrs Asitdirectlyopposite each other and (at the

same time - this isonequestion) Mr and Mrs Bwon’tsitnextto each other.

Thanks
