1.6 Notes: Probability Warm-up Write each number as a percent. 1) 8 3 2) 0.0043 3) 1 6 5 Objective: - to find experimental probabilities - to find theoretical probabilities Experimental Probability The experimental probability of event = P(event) = number of times the event occurs / number of trials 1) A baseball player got a hit 21 times in 60 at-bats. Find the experimental probability of his getting a hit. P(hit) = ? 2) A basketball player has made 32 free throws in 50 tries. What is the experimental probability of her making a free throw? P(free throw) = ? Using a Simulation Everyone go up to the board and write out the month you were born. What’s the experimental probability of someone in this class being born in February?

Unformatted text preview: P(February) = ? Theoretical Probability When you roll a dice (or a number cube) the possible outcomes are 1,2,3,4,5, and 6. We call all possible outcomes the sample space . Theoretical probability is calculated as a ratio of outcomes. Theoretical probability of x = x / sample space 1) What is the theoretical probability of rolling an even number on a number cube? P(even) = ? 2) Find the theoretical probability of getting a prime number when you roll a number cube. P(prime) = ? 3) A jar contains 20 red marbles, 30 blue marbles, and 50 green marbles. What is the theoretical probability of each: P(red) = P(blue) = P(green) =...
