This video tutorial explains how to use proportions to make predictions with probabilities. It provides two examples: predicting how many days pizza will be chosen for dinner using a spinner, and predicting how many times Miss Urban's name will be drawn from a bowl. The tutorial demonstrates setting up and solving proportions to estimate outcomes based on theoretical probabilities. It concludes with a summary of the process for predicting events using probability and proportions.
