Simple Probability

The video tutorial covers the concept of simple probability using a marble selection problem. It begins with a problem statement involving Jacinta selecting a marble from a bag containing blue, red, and green marbles. Viewers are encouraged to pause and solve the problem before proceeding. The tutorial then explains the setup, counts the marbles, and discusses the concept of simple probability as a ratio of desired outcomes to possible outcomes. The probability of selecting a green marble is calculated, and the lesson concludes with a summary.
