This program covers the important topic of combinations in Probability and Statistics. We begin by discussing what a combination is and why it is a central topic in probability. Next, we solve several problems that involve combinations to give students practice with the material. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long-term memory.
