Choosing Marbles

Focus Question: 

How do we determine the theoretical probability of some slightly more complex situations.

New Vocabulary:

• AND - All conditions described must be met.
• OR - Only one of the conditions described need to be met.
• NOT - The conditions listed must NOT occur.

Part 1: More Kalvin

For this part of the lesson you are going to do a quick formative assessment to see how well you understand the main focus questions from last week's lessons on probability.

You will do the assessment independently and can use calculators if you think that you need them.

Part 2: Simple Events

In this part of the lesson you will watch a video describing some of the basics around finding the theoretical probability of an outcome for a given event.  We have already talked about this a little bit, so this should be mostly a reinforcement of prior knowledge.

When you have finished watching the video, make sure that you complete the "On Your Own" questions.  Show your teacher when you have finished the questions.

Part 3: Choosing Marbles - Determining Theoretical Probabilities

The main part of this lesson is for you to now practice applying the concept of theoretical probability.  This is also in your textbook on page 30.

By the end of this problem you should be able to do the following:

• Determine the theoretical probability for a series of outcomes that contain the "OR", "AND", and "NOT" conditions.
• Develop a probability situation based on theoretical probabilities.
