Your Canadian, long weekend bonus math puzzle.
Oh, heck, open for solutions. Go wild.
At a terminal gate at Calgary airport, you have 100 young, male members of the CPC, standing patiently in line to board their 100-seat plane where they will fly to Parliament Hill to demonstrate against same-sex marriage because, as we all know, allowing same-sex marriage would cheapen the sanctity of their sitting in the dark of their parents' basement, snarfing down Cheeto-s and masturbating to online, photoshopped pictures of Rachel Marsden. But I digress. Onward.
Every passenger has a boarding pass with a pre-assigned seat number but, as the very first passenger makes his way down the JetWay, he loses his pass. Because of this, upon entering the plane, he simply picks a random seat and sits down.
Subsequently, each passenger, upon entering, goes to his pre-assigned seat and, if it's empty, sits there. If someone is already in it, he randomly picks an empty seat and sits there instead. And so on, and so on.
What are the odds that the very last passenger to board will actually get to sit in his original, pre-assigned seat?
