Bell Ringer -2(3 + 6v) = -5v – 25 -6 – 12v = -5v – 25 + 6 + 6 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!
On the back of your score sheet: 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?
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.
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.
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 2 . 1 13 1 26 = 1 2 . 3 13 3 26 =
