# MA.7.DP.2.2

Given the probability of a chance event, interpret the likelihood of it occurring. Compare the probabilities of chance events.

### Clarifications

Clarification 1: Instruction includes representing probability as a fraction, percentage or decimal between 0 and 1 with probabilities close to 1 corresponding to highly likely events and probabilities close to 0 corresponding to highly unlikely events.

Clarification 2: Instruction includes P(event) notation.

Clarification 3: Instruction includes representing probability as a fraction, percentage or decimal.

Introduction to Probability:

This resource is designed to introduce students to the concept of probability: the probability of a rare event is represented by a positive number close to zero, the probability of a nearly certain event occurring is represented by a positive number slightly less than one. Students will indicate the approximate probability of events on a number line and determine which events are more likely than others.
