Pre-AlgebraExperimental ProbabilityLets Experiment!!Pretend that you have a number cube.You are going to roll it one time.What is the theoretical probability of getting each number?P(1)P(2)P(3)P(4)P(5)P(6)Lets Experiment!You are going to conduct a probability experiment!You are going to toss a dice 30 times.Record the number of times each number appears!!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)Answer me this!!How did you find the experimental probability?In your own words, what is experimental probability?What is the difference between theoretical and experimental probability?What Are You Learning?I CAN find the experimental probability.Why Do You Need To Know This?Experimental Probability is useful in finding the number of outcomes for various real life experiments.There are cards numbered 1-10 in a bag. 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(7)P(8)P(9)P(10)P(even #s)P(odd #s)Lets Experiment!!Each group has a baggie with the numbers 1-10 inside.One member of the group needs to pick a number, record the number, and replace the number in the bag.This needs to be done 20 times. Be sure to record your results after each pick.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(7)P(8)P(9)P(10)P(even #s)P(odd #s)Answer me this!!How did you find the experimental probability?In your own words, what is experimental probability?What is the difference between theoretical and experimental probability?VocabularyExperimental Probabilitynumber of times an event occursnumber of times experiment is doneTwo 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(9) = # of times a sum of 9 occurs # of possible outcomesThats My Favorite Color!!A spinner is spun 50 times and it lands on the color blue 15 times. What the experimental probability of spinning blue?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?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? 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? In a survey, 50 people were asked to pick which movie they would see this weekend. 20 chose Horror Story15 chose The Ink Well10 chose The Monkey House5 chose Little Rabbit. What is the experimental probability of someone wanting to see The Monkey House?Class WorkSheet 9-6
