Probability of Compound Events

The video tutorial explains how to calculate the probability of multiple events occurring by multiplying the probabilities of individual events. Using a spinner with 12 equal parts, where 2 are winning sections, the tutorial demonstrates how to find the probability of landing on a winning section in two consecutive spins. The probability is calculated by reducing the fraction of winning sections and multiplying the probabilities of each spin. The concept of compound events is also discussed, emphasizing the multiplication of individual event probabilities.

What is the first step in finding the probability of multiple events occurring?

• Add the probabilities of each event.

• Multiply the probabilities of each event.

• Subtract the probabilities of each event.

• Divide the probabilities of each event.
