The formula is n(n-1)/2, for 8 people this is 8*7/2 = 28.

8 persons each have 7 people to shake hands with, but then you have counted each handshake twice (from the perspective of both participants), so you have to divide by 2.

Its to delete the files from the computer that you no longer want. Once its put in the recycling bin it stays there, then when you empty it, its off your computer and there is no way you can get those files back.

professor190 [17]
<span>I can't imagine any reason "why" he should have behaved in such an extraordinary way. If we were to use "how" in that sentence it would contradict the context. We are obviously talking about a situation that has happened so we know that "he" has in fact acted in an extraordinary way but we don't know "why" he acted that way. Therefore "why" is the correct term to use.</span>
