: How can we determine the probability of a compound event?AIM Sample Space Worksheet (downloadable copy found in the resource section)HW:Do Now:Michelle was rolling a number cube. She recorded the results in the following table. What was her experimental probability of rolling an even number? Number | 1 | 2 | 3 | 4 | 5 | 6 | Frequency | 2 | 3 | 6 | 3 | 5 | 1 | Classwork:In previous lessons, we learned to find the probability of one event--such as rolling a number cube, or spinning a spinner, or flipping a coin, or picking colored tiles from a container. Today we looked at how probability works when there is a compound event, which is when two or more events happen at once. Examples of compound events include finding the probabilty of flipping a coin and getting a heads AND drawing a heart from a deck of cards. We use sample spaces to organize all of the possible outcomes that can happen. From there, we can determine probabilities of compound events. The sample spaces that we will be working with are: tree diagrams, lists, and area models.
