The first example we saw was a continuation from yesterday. Here are two more solutions, one using a combination and one using a permutation.
Here's another example showing how to use permutations to find probability. The reason it is a permutation is because the order matters in this case.
This example is a similar question, but order doesn't matter, so we used a combination.
We also
received the key for the pretest, so don't forget to prepare for the test
tomorrow. Remember that we will be using calculators.
