The conditional probability of an event B, in relation to event A, is the probability that event B will occur given the knowledge that an event A has already occurred.
Listen, there are VERY FEW times in your Algebra 2 classes that you get to just HAVE FUN teaching a lesson! Don't let this opportunity pass you by. I always spend more time on this lesson than I should. Why? Because it is a point in the course where you can re-ignite your students interest in your class.
There are so many activities you can do to help you teach this lesson and get your students truly involved I could never list them all. But here are my top 5!
Everybody Loves Candy
Split your class into groups, give them a bowl of M&M's or Skittles, give them a list of questions on finding different probabilities for drawing the right color. Watch them enjoy. If you want to make it more exciting then have them also do the activity with a blind fold on and ACTUALLY pick random candy out of the bowl.
Another small group activity. Same concept but more realistic. Deal out hands of cards to each member of the group. Have them figure out what the probability of the next card will be.
