Permutations again!?!

Today we discussed more in depth the probabilities associated with counting problems. That means that we look at a counting problem, then consider a probability sort of question. It's important to remember here the definition of probability and use it for part marks.

Specifically you want to make sure you calculate the total number of possible outcomes (which will be the easier of the counting problems) for part marks. Be sure to take a look at the examples and give the assignment a try. We'll discuss any problems you have tomorrow.
