Lesson 086: Introduction to Probability

Aim: How do we use math to explain the likelihood of an event occurring?

Learning Objective: I CAN explain probability in terms of certainty and uncertainty.

Essential Questions:
When is it important to collect and organize data?
How can collecting and organizing data help you to make decisions and predictions?
How do certain careers utilize the summary of data sets?

event, Ccance, certain, impossible, unlikely, likely

Criteria for Success
Express probability of an event as a fraction (desired event/all possible event)
Convert fractions as a percentage
Contextualize event in context of probability
