# Psychic Ken

By using some simple properties of numbers it is quite possible for a mathematician to convince people that they possess psychic powers! Here is a simple example.

## The puzzle

- Think of a number between 1 and 10
- Multiply that number by 9
- Add the digits of this result together
- Subtract 5 from this result
- Find the letter that corresponds to this number, where 1=A, 2=B, 3=C etc
- Think of a country that starts with this letter
- Think of an animal that starts with the second letter of that country's name
- I predict that your animal is grey in colour.

This prediction will be correct more often than not. How did I do it?
