13. Use a number from 0 to 1 to represent the probability of a chance event occurring, explaining that larger numbers indicate greater likelihood of the event occurring, while a number near zero indicates an unlikely event.
[MA2019] REG-7 (7) 14 :
14. Define and develop a probability model, including models that may or may not be uniform, where uniform models assign equal probability to all outcomes and non-uniform models involve events that are not equally likely.

a. Collect and use data to predict probabilities of events.

b. Compare probabilities from a model to observed frequencies, explaining possible sources of discrepancy.
[MA2019] REG-7 (7) 15 :
15. Approximate the probability of an event using data generated by a simulation (experimental probability) and compare it to the theoretical probability.

a. Observe the relative frequency of an event over the long run, using simulation or technology, and use those results to predict approximate relative frequency.

Title: Grade 7 Mathematics Module 5, Topic A: Calculating and Interpreting Probabilities
URL: https://www.engageny.org/resource/grade-7-mathematics-module-5-topic-overview
Description:

In Module 5, Topics A and B, students learn to interpret the probability of an event as the proportion of the time that the event will occur when a chance experiment is repeated many times (7.SP.C.5). They learn to compute or estimate probabilities using a variety of methods, including collecting data, using tree diagrams, and using simulations.

16. Find probabilities of simple and compound events through experimentation or simulation and by analyzing the sample space, representing the probabilities as percents, decimals, or fractions.

a. Represent sample spaces for compound events using methods such as organized lists, tables, and tree diagrams, and determine the probability of an event by finding the fraction of outcomes in the sample space for which the compound event occurred.

b. Design and use a simulation to generate frequencies for compound events.

c. Represent events described in everyday language in terms of outcomes in the sample space which composed the event.

Title: Grade 7 Mathematics Module 5, Topic B: Estimating Probabilities
URL: https://www.engageny.org/resource/grade-7-mathematics-module-5-topic-b-overview
Description:

In Module 5, Topic B, students move to compare probabilities from simulations to computed probabilities that are based on theoretical models (7.SP.C.6, 7.SP.C.7). They calculate probabilities of compound events using lists, tables, tree diagrams, and simulations (7.SP.C.8). They learn to use probabilities to make decisions and to determine whether or not a given probability model is plausible (7.SP.C.7). The Mid-Module Assessment follows Topic B.

Title: Plinko Probability
URL: https://phet.colorado.edu/en/simulation/plinko-probability
Description:

In this PhET activity, students will drop balls through a triangular grid of pegs and see them accumulate in containers. Switch to a histogram view and compare the distribution of balls to an ideal binomial distribution. Adjust the binary probability and develop your knowledge of statistics! This activity could be used to help teach a lesson on probability. This Phet activity can be downloaded and assigned to Google Classroom.
