+6226 I call up it's easiest to count the ways that they can consecutively sit down together and decrease this from the total number of seating arrangements.
At that place are 6 groups of 3 consecutive seats. Inside each group there are 3!=half dozen ways the three fussy people tin be bundled.
And so the remaining five people can be arranged 5!=120 ways in the remaining seats.
So there are 6*6*120 = 4320 arrangements where they Practice sit consecutively
There are 8! = 40320 total arrangements.
So there are 40320 - 4320 = 36000 arrangements where the iii exercise non sit down consecutively.
