Design and conduct a statistical experiment to study a problem.

Lesson 8.1.2-1 Objectives

Construct sample spaces of chance situations involving equally likely outcomes

Construct probability distributions from sample spaces.

Compute P(A and B) using the Addition Rule or its special case for mutually exclusive events

Essential QuestionUnder what conditions can you add individual probabilities to

find the probability that a related event happens?

In Investigation 8.1.1 you constructed the probability distribution for the sum of two dice. You discovered that to find the probability that the sum is 2 or 3, you could add the probability that the sume is 2 to the probability that the sumIs 3.
