## Probability Explained!

This math video tutorial explains how to solve probability word problems using marbles as examples. It provides a basic review of calculating probability for independent events. It goes over the rules of compound events focusing on key expressions such as and/or. “And” is associated with multiplication while “or” is associated with addition. This video contains plenty of examples and practice problems of calculating probability with replacement and without replacement.
