Understanding Probability and Likelihood

The video tutorial introduces the concept of probability, focusing on the terms 'certain', 'impossible', 'likely', and 'unlikely'. It explains these terms with examples, such as the certainty of the sun rising and the impossibility of a shark flying. The tutorial then introduces 'likely' and 'unlikely' events, providing examples like seeing a kangaroo or drinking water. The video concludes with an activity for students to identify and illustrate likely and unlikely events in their own lives.
