8. The Last Supper On the last night of Scout camp, Chris, his wife Jo and the 11 other adults sit down for
supper along one side of a long rectangular table.
Chris takes the central seat, with six adults on each side of him.
Jo must sit next to Chris.
Alex, Barb and Dave insist on being next to one another (in any order) on the side to
Chris's left.
Eddie, Fred and Gareth are fed up with Alex's snoring, so they refuse to be on the same
side of Chris as him.
Heather, Iris, Kane, Luke and Michael have no seating preferences.
How many arrangements of the adults are possible?

The number of possible seats is an illustration of permutation

There are 1728 possible sitting arrangements

From the question, we have the following highlights:

So, the number of sitting arrangement is:

Evaluate the product

Hence, there are 1728 possible sitting arrangements

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
