Probability Trees: Calculating Probabilities of Combined Events

The video tutorial explains probability trees, a tool for calculating probabilities of combined events. It uses an example of drawing colored balls from two bags to illustrate how to construct and use probability trees. The tutorial covers calculating probabilities by multiplying along branches and adding probabilities for multiple outcomes. It emphasizes the importance of ensuring branches sum to one and provides a recap of key principles.
