A compound event is made of two or more simple events; when they are independent, the probability that both happen is P(A and B) = P(A) x P(B). This worksheet teaches the multiplication rule with a tree diagram and has students compute probabilities.
The reference box and Section A are on page 1. The reference box shows a tree diagram of flipping a coin twice. Section A has six probability problems. Section B on page 2 has four word problems.
Page 3 is a complete answer key with the probability for every problem. The worksheet pairs well with the Simple Probability and Reading Tables worksheets.
