Question 1075744
Here's my guess:
Let the people be called
A, B, C, D, E
Let the people who must sit next to eachother
be A and B
--------------
Let ( A,B ) be considered a "position", so now
there are 4 "positions"
( A,B ), C, D, E
There are 4 ways to fill the 1st position
There are 3 ways to fill the 2nd position
There are 2 ways to fill the 2nd position
There is 1 way to fill the 4th position
{{{ 4*3*2*1 = 24 }}}
I must double this since I could have either
(A,B) or (B,A) so there are
{{{ 2*24 = 48 ways to seat the 5 people
--------------------------------------
definitely get another opinion!
