Probability and Likelihood Concepts

The video introduces the concept of probability, explaining it as the likelihood of an event occurring. It uses examples like colored balls in a box and a spinner to illustrate how probability can be measured using numbers or descriptive words. The lesson concludes with a call to action for viewers to take a quiz to reinforce their learning.
