Countdown to Exams - Day 67 - Probability

Today we shift our focus to the Statistics section and focus on the topic of Probability. Here we take an introductory look at probability and using a sample space diagram to identify the number of outcomes. You should know that all probabilities from an event add up to make 1. Take care when calculating probabilities as your answer can be in the form of fractions (simplify them), decimals, and percentages so you may need to convert between them. We cover the 'or' rule for mutually exclusive events and the 'and' rule for independent events.

In the video below, Matt introduces the topic of probability and calculating probabilities.
