Probability and Event Likelihoods

The video introduces the concept of probability, explaining it as the likelihood of an event occurring. It uses examples like colored balls and a spinner to illustrate how probability can be measured using numbers or descriptive words. The lesson includes questions to reinforce understanding and concludes with a prompt for a quiz to further explore the topic.
