# Introducing Independence: Does Mrs. Gallas choke under pressure?

Updated: Aug 16, 2020

Testing if two events are independent is tough. And with a formula like P(A) = P(A|B) = P(A|not B) it can be very confusing! Our students are always messing up the conditional probabilities so they usually find the events are dependent since the probabilities are not equal.

So how can we get our students to do better with probability? This starts with a strong focus on conceptual understanding. We try to avoid formulas at all costs! When students memorize rules and formulas they don't do as well because they don't understand what they're doing. They're just replicating what they've seen.

Last year, students had the hardest time understanding how to determine if two events were independent. So this year we're going to take a little extra time to work on developing this idea with this new lesson.
