This video tutorial covers the basics of probability, explaining it as a ratio of successful outcomes to total outcomes. It demonstrates how probability can be expressed as a fraction, decimal, or percentage. The tutorial provides examples, such as calculating the probability of drawing a yellow ball from a box. It also explores the concept of independent and dependent events, using experiments with colored balls to illustrate. The video concludes with a discussion on calculating the probability of multiple events, such as drawing cards from a deck, emphasizing the use of complementary probabilities.
