4. Anticipatory Set
The other day we completed an experiment involving rolling
two dice to find what the most frequently occurring sum would
be. Today we will find the theoretical probability of each sum
occurring.
1.) Based on the Fundamental Counting Principle, how many
possible outcomes can there be for rolling two six sided dice?
