COUNTING AND PROBABILITY

In this unit, you will look at arrangements of letters, numbers, and words. You will first explore listing all possible outcomes through tables, grids, and tree diagrams. You will then connect this process of determining outcomes to the Fundamental Counting Principle, combinations, and permutations. You will also examine the “odds” of favorable and unfavorable outcomes.
