Understanding Probability Concepts

The video tutorial explains how to calculate the probability of landing on a multiple of three using a spinner with eight sections. It covers determining total and favorable outcomes, simplifying the probability fraction, and converting it to decimal and percentage forms. The tutorial concludes with an explanation of expected outcomes based on the calculated probability.

What is the first step in determining the probability of an event?

• Spinning the spinner

• Calculating the percentage

• Identifying the favorable outcomes

• Counting the total number of outcomes
