You pick one card at random. Find the theoretical probability of each event.P(1)P(2)P(3)P(4)P(5)P(6)</p><p>P(7)P(8)P(9)P(10)P(even #s)P(odd #s)</p></li><li><p>Lets Experiment!!Each group has a baggie with the numbers 1-10 inside.</p><p>One member of the group needs to pick a number, record the number, and replace the number in the bag.</p><p>This needs to be done 20 times. Be sure to record your results after each pick.</p></li><li><p>Based on the results of your experiment, find the experimental probability of each event.P(1)P(2)P(3)P(4)P(5)P(6)</p><p>P(7)P(8)P(9)P(10)P(even #s)P(odd #s)</p></li><li><p>Answer me this!!How did you find the experimental probability?</p><p>In your own words, what is experimental probability?</p><p>What is the difference between theoretical and experimental probability?</p></li><li><p>VocabularyExperimental Probability</p><p>number of times an event occursnumber of times experiment is done</p></li><li><p>Two number cubes are rolled 75 times and a sum of 9 is rolled 10 times.What is the experimental probability of rolling a sum of 9?</p><p>P(9) = # of times a sum of 9 occurs # of possible outcomes</p></li><li><p>Thats My Favorite Color!!A spinner is spun 50 times and it lands on the color blue 15 times. </p><p>What the experimental probability of spinning blue?</p></li><li><p>The graph shows the results of an experiment in which a coin was tossed 30 times. What is the experimental and theoretical probability of tossing tails?</p></li><li><p>The graph shows the results of an experiment in which a number is rolled 30 times. What is the experimental and theoretical probability of rolling a 5? </p></li><li><p>In a survey, 100 people were asked to name their favorite Independence Day side dishes. What is the experimental probability of macaroni salad being someones favorite dish? </p></li><li><p>In a survey, 50 people were asked to pick which movie they would see this weekend. 20 chose Horror Story</p><p>15 chose The Ink Well</p><p>10 chose The Monkey House</p><p>5 chose Little Rabbit.
