Understanding Probability Concepts

The video tutorial introduces probability vocabulary, explaining terms like impossible, certain, possible but unlikely, and possible and likely. It provides examples for each term to illustrate their meanings. Impossible events are those that will never happen, while certain events are guaranteed to occur. Possible but unlikely events have a chance of happening but probably won't, whereas possible and likely events have a good chance of occurring.
