  4. Learning Goal • SWBAT find the theoretical probability of an event

  5. Section 10.2 “Experimental Probability” Remember this??? Experimental probability- comparing the number of times the event occurs to the number of trials

  6. Section 10.4 “Theoretical Probability” Theoretical probability- finding the probability of an event when all outcomes are equally likely. If each possible outcome of an experiment is equally likely, then the experiment is said to be FAIR

  7. Find the probability of each event. Write your answer as a fraction, percent, and decimal (rounded to the nearest hundredth). • Rolling a number greater than 2 on a fair number cube • Randomly choosing an orange chip from a bag of 14 green chips, 4 blue chips, and 12 orange chips

  8. “Roll the Dice” • Suppose you are rolling a two fair number cubes and finding the sum of the rolls. Find the probabilities as a fraction, percent and decimal (rounded to the nearest hundredth). Sample space What is the probability that you will roll a 7? What is the probability that you will roll a prime number?

  9. “Pick a Card” • Suppose you are randomly choosing cards from a shuffled deck of 52 cards with 13-card suits: diamonds, hearts, clubs, and spades. (Round your answers to the nearest hundredth if necessary). What is the probability that you choose a 7 of hearts or diamonds? What is the probability that you will pick a King, Queen, Jack, or Ace?
