Probability

The students started their probability unit at the end of last week and will dive deeper into the unit this week. We will talk about mutually exclusive events, independent events, and dependent events. The students seem to be excited about working with probability and connecting it to events they have seen in their life all ready. Ask your students what the probability of 1 means (the event is certain to occur) and what the probability of 0 means (the event is impossible).

Last week, the students took their Unit 9 Test which will be passed back this week. Please encourage your student to do test corrections if he/she did not do as well as they would have liked on their test.
