## 1 The 5-Card Effect

On Friday 4th, March, 2011, a magical effect was performed in class. The student is asked the following:

- Describe the magic effect.
- Find out what the mathematical idea behind the magic effect is. Describe those mathematical ideas in terms of combinatorics principle.
- For the following sets of cards, describe the magic effect. Find which card you should give the volunteer and which to the magician, and, quite important, in which order.

- Be ready to be called and performed the magic effect for me if I do not fully understand your description.

NOTE: This magic effect can be performed in many ways. If you come up your own magic effect, please, describe it thoroughly. It may different from the one performed in class, but it will be equally valid.
