Lesson 10-5 Experimental Probability Obj: The student will be able to 1) Determine the experimental probability of an event 2) Use experimental probability to make predictions HWK: Vocab: 1) experiment 2) trial 3) outcome 4) sample space 5) event 6) probability 7) experimental probability 8) prediction COS: S-CP1

Identify the sample space and the indicated outcome for each experiment. Ex 1) Tossing two coins Ex 2) Rolling a number cube/ getting a 3 Sample space: Sample space: Outcomes: Outcome:

Ex 3) Spinning a game spinner marked yellow, green, red and blue/ spinning green Sample space: Outcome:

Probability

Ex 4) Write impossible, unlikely, as likely as not, likely, or certain to describe each event. Explain a) A coin lands head up b) There are 31 days in August c) Cecilia rolls a 10 on a standard number cube d) Carlos correctly guesses a number between 1 and 1000

Spinner does not land on green Spinner lands on red Ex 5) An experiment consists of spinning a spinner. Use the results in the table to find the experimental probability of each event. Spinner lands on blue Spinner does not land on green Spinner lands on red Spinner does not land on blue

Ex 6) A manufacturer inspects 800 light bulbs and finds that 796 of them have no defects. What is the experimental probability that a light bulb chosen at random has no defects (express as a percent) Predict the number of light bulbs in a shipment of 2400 that are likely to have no defects.
