In this lesson, we are going to talk about making choices and that is going to lead us into combinations and permutations. There are lots of problems in probability where they say something like how many different ways are there to choose from? These problems are some of the most confusing ones in probability. Through the examples in this lesson, we will try to better understand these problems and learn how to apply the right formula. You should pay attention to terms like with replacement, without replacement, or ordered and unordered, because these are the ones that make the difference.
