Exploring Simple Probability Concepts

This video tutorial covers the basics of simple probability, explaining it as the ratio of favorable outcomes to total outcomes. It includes examples using a spinner, socks in a basket, dice, and movie genres to illustrate how to calculate probabilities. The concept of complementary probability is also discussed, emphasizing that the sum of probabilities of an event and its complement equals one.
