  1. Bell Ringer Solve for x. Round your answer to the nearest whole number. -2(3 + 6v) = -5v – 25 -6 – 12v = -5v – 25 + 6 + 6 -12v = -5v – 19 + 5v + 5v -7v = -19 -7 -7 v = 2.71 = 3 Huh? What? How did you get 3? I’m lost!

  2. Pig Reflections On the back of your score sheet: • How did you decide whether or not to roll again? • What strategies did you try? Which worked best for you? • If you were playing for a prize, would your strategy change?

  3. Two Independent Events • Two specific events are considered independent if the outcome of one event has no effect on the outcome of the other event. • Tossing a coin and drawing a card are independent events because the outcome of either event has no effect on the other.

  4. Two Independent Events • To find the probability of two independent events occurring together, multiply their probabilities! • Ex. Find the probability of tossing a coin twice and having heads occur twice. Probability of two heads! . 1 2 1 2 1 4 = Probability of Toss #1 coming up heads. Probability of Toss #2 coming up heads.

  5. Independent Events Ex. A coin is tossed and a card is drawn from a standard deck. a. What is the probability of tossing heads and drawing an ace? b. What is the probability of tossing tails and drawing a face card? . 1 13 1 2 1 26 = . 3 13 1 2 3 26 =
