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.

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.
