LESSON: Conditional Probability

Before we generalize the conditional probability rule, it's important for us to get some practice finding "joint" probabilities, or probabilities that include the $$\bigcap$$ symbol, meaning "and". 

When looking for joint probabilities, we're looking for two events that occur together. At the beginning of the following lesson video I will go over a few examples of finding joint probabilities. Following that you will see the formal conditional probability rule.
