  1. Let’s Review Probability is the chance of an event happening. 1. What is the probability of rolling a number less than three on a number cube (die)? 2. A game requires spinning the spinner shown below. If the number spun is greater than 3, the player wins. What is the probability of winning the game? 3. What is the probability of not winning?

  2. Independent Events Independent events are two or more events in which the outcome of one event does not affect the outcome of the other event(s).

  3. Independent Probability with Sample Spaces What are all of the possible outcomes of spinning the spinner and rolling the number cube? A1 B1 C1 A2 B2 C2 A3 B3 C3 A4 B4 C4 A5 B5 C5 A6 B6 C6 What is the probability of spinning C on the spinner and rolling an even number on the number cube?

  4. Independent Events with Sample Spaces • What are all of the possible outcomes of children in a family with three children? • B= BOY • G= GIRL BBB BBG BGB GBB GGB GBG BGG GGG Other than listing the sample space, how could you find the number of outcomes possible?

  5. Independent Events Sometimes listing the sample space to find probabilities is long and time consuming. To find the probability of independent event, multiply the probability of each event. The product is the answer.

  6. Independent Probability What is the probability of spinning C on the spinner and rolling an even number on the number cube? CEven = X =

  7. Independent Probability The spinner below is spun and a number cube is tossed. Find the probability of spinning a C and rolling a number less than 5. Spin a C# < 5 = X

  8. Independent Probability For lunch, Jessica may choose a turkey sandwich, a tuna sandwich, a salad, or a soup. For a drink, she can choose juice, milk, or water. If she chooses a lunch and a drink at random, what is the probability that she chooses a sandwich and juice? lunchdrink X =

  9. Independent Probability A coin is tossed and a number cube is rolled. Find the probability of tossing heads and rolling an even number. Headseven # X =

  10. Independent Probability Zachary has a blue, a red, a gray, and a white sweatshirt. He also has blue, red, and gray sweatpants. If Zachary randomly pulls a sweatshirt and a pair of sweatpants from his drawer, what is the probability that they will both be blue? shirtpant X =

  11. Independent Probability By rolling a dice and spinning the spinner below, find: P(prime # and red or blue)= PrimeR or B = X =

  12. Independent Probability A coin is flipped 3 times. What is the probability of getting tails on all three flips? flip 1flip 2 flip 3 X X =
