3. Sample Space: A list of all possible outcomes Example: Tossing a coin – heads, tails Theoretical Probability: analyzing a situation Experimental Probability: actually finding the probability

4. Example 1 The spinner is spun once. What is the probability, chance, and odds that the spinner will stop a. on a 2? b. on a prime number? 2 3 3 2 1 2 3 1

5. Example 2 The spinner is spun twice. Find the probability of spinning C once not a D AB C D

6. Example 3 A coin is flipped twice. What is the sample space? What is the probability of getting at least a tails? First toss Second Toss H T H T

7. Example 4 A coin is flipped three times. What is the sample space? What is the probability of getting a tails at least two time?
