Answer to 'Wheel Rotation Probability'

I've recently been reading a bunch of software engineering books in an attempt to improve my skills. This is no mean feat, as I'm already the best programmer in my company. Code Complete is absolutely the best book I've ever seen on the subject. It is a must read for everyone who wants to program. I would make it required reading for all students and computer professionals. It's very readable, and if you follow it's advice it will change your life.

For the first tire there is a 1 in 4 chance that the chosen tire is in the correct position.

For the second tire there is a 1 in 3 chance that the chosen tire is in the correct position.

For the third tire there is a 1 in 2 chance that the chosen tire is in the correct position.

For the fourth tire there is a 1 in 1 chance that the chosen tire is correct because it is the last one.

Therefore,

The Answer = 4*3*2*1

The Answer = 24

Therefore, there is a 1 in 24 chance that all of the tires are put in the same wheel well as the one they were taken from.
