Magic trick (Posted on 2007-05-11) Difficulty: 3 of 5
Two magicians A and B perform the following trick:

A leaves the room and B chooses 4 members from the audience at random. Each member chooses a card numbered from 1 to 100 (each chooses a different card) and after B has seen their cards he chooses a card from the remaining deck of cards. The 5 chosen cards are shuffled by an audience member and handed to A who just returned to the room. Prove that A is able to figure out which cards each member picked. Consider that the chosen members form a row and e.g. the leftmost member picks the first card and the rightmost member (B) picks the last card.

Ady,
I received your email with the explanation that you have posted. I have advised that I want to consider this further.

In the meantime, might you look at how you might reformat that to which I am replying?  It looks like you have an MS Outlook/FrontPage format, I am guessing as I don't use either.
