Randomlydraw two marbles from the box, record each color, and then return the marbles tothe box. Repeat this procedure 50 times.1. Based on your results, what is the experimental probability of selecting two yellowmarbles?2. Based on your results, what is the experimental probability of selecting a green marbleand a yellow marble?3. Compare your results to the theoretical probabilities.4. Color blindness occurs in 4% of the male population. What could you use to simulate thissituation?SCHOOL CURRICULUM For Exercises 5–8, use the following information.Laurel Woods High randomly selected studentsfor a survey to determine the most importantschool issues among the student body. Theschool wants to develop a curriculum thataddresses these issues. The survey results areshown in the table.5.

Based on the survey, what is the experimental probability that a student chosen atrandom thinks the most important issue is grades or school standards?7. The enrollment in the 9th and 10th grades at Laurel Woods High is 168. If theiropinions are reflective of those of the school as a whole, how many of them would youexpect to have chosen popularity as the most important issue?Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc.8.
