  1. After 50 spins, Chris landed on green 22 times. What is the experimental probability of landing on green? Write the fraction, decimal and percent. How does it compare to the theoretical probability? Bell Work Experimental: 22/50 = 11/25, .44, 44% Theoretical: 3/8, .375, 37.5%

  2. Experimental Probability Day 2

  3. In a school of 300, Chris surveyed 80 students and found that 44 students prefer chocolate ice cream. How many out of the 300 students can you predict to choose chocolate? Predictions According to the survey results, we can predict that 165 students at Chris’ school prefer chocolate ice cream.

  4. Karen spun a spinner 50 times and recorded her results in the table below. The spinner had five numbered sections. Based on the results in the table, how many times should Karen expect the spinner to land on section 3 or 4 if she spins the spinner 300 times? 132 times

  5. The mayor of a town conducted an opinion survey of 90 randomly selected voters. The mayor wants to determine if a new shopping mall should be built in town. The survey results are shown below. There are 1,440 voters in town. How many voters would be expected to want the new shopping mall built? 960 voters

  6. The spinner below is spun 20 times. The table shows the results. Based on these results, how many times would 2 be expected to appear in 60 spins? 24 times

  7. According to the experiment below what is the probability of rolling a 7 with two die? What is the theoretical probability of rolling a seven? P(rolling a 7) = 3/10

  8. Skills Check! When you finish turn your paper over, put it in the corner of your desk and work on your practice. Practice: Probability worksheet Day 2
