« The
Monty Hall Dilemma V3 »
pdf, 2015, 28 pages
The
Monty Hall problem is a famous one in probability. It is based on a
TV game from the USA called ”Let's make a deal” (1963). It is
named after the host of this show.
Inspired by this game, here is an original effect and a
great plot for stage, parlour or close up. This unpublished method
is easy to do and costs nothing. There is no maths or memorization or
difficulty of any sort. It does require some one-time preparation,
but just with some index cards, a sheet of paper (for the list of
prizes), and a normal pen, nothing else. It can be adapted to your
style, venue, weddings, birthday
parties, Halloween, Valentine day, corporate
events, kids shows, etc. The list of booby prizes can also be VERY easily
customized or changed for strolling, and be a good opportunity for
comedy Magic!
Effect :
Three
business cards are put on the table, along with a list of random
lottery numbers and prizes. Two of the cards have a lottery number
written on the back, and the third one has a car. The spectator
chooses one of the cards, WITHOUT LOOKING AT IT. The performer looks
at the three cards, and turns over one that he knows is a booby prize
card of course. The spectator is now invited to either keep his
original card, or to swap it against the other one. Whatever he
does, he will always
(100% suresafe) lose. (You can also make the spectator win all the time, if you prefer.)
Note:
The performer can also predict whether the spectator would switch or
not.
