Relative Frequency and Probability

The video tutorial explains how to calculate relative frequency using a spinner divided into green, yellow, and blue sections. The spinner is spun 200 times, and the video guides viewers through predicting the number of times the spinner will land on each color. It uses proportions to determine the expected outcomes based on the probability of each color. The tutorial covers calculating the relative frequency for green, yellow, and blue sections, demonstrating the use of equivalent ratios and proportions to predict outcomes.

What is the main task described in the introduction of the video?
