Read Carefully! This assignment must be turned in to your math teacher within two weeks of returning to school. This assignment will be graded as a homework assignment. Your math teacher will be available for questions about this assignment upon returning to school from 7:10 am until 7:30 am.

Open the link below to spin an online spinner. If you have trouble accessing this website, use the data provide to complete the experimental probability.

**Remember P(blue) is read as the probability of blue.

**Theoretical probability is a comparison of the number of favorable outcomes to the number of possible equally likely outcomes.

P(event) = number of favorable outcomesnumber of possible outcomes

1.)  Using the spinner on the above website, or looking at the above spinner, list the theoretical probability for each color, if the spinner is spun 50 times. Be sure to simplify fractions to lowest terms!

Color / P(red) / P(orange) / P(purple) / P(yellow) / P(green)
Theoretical Probability

**Frequency means the number of times an event occurs.

2.)  If you have access to the above website, spin the spinner 50 times and then organize your results in a frequency table. If the above website is not working, use the following data: A spinner is spun 50 times. The data for the 50 trials is listed below.

Color / Tally Mark / Frequency
Red
Orange
Purple
Yellow
Green

red, purple, orange, yellow, red, yellow, green, purple, green, yellow, red, purple, orange, orange, orange, orange, purple, red, yellow, green, orange, red, green, red, yellow, green, green, red, orange, yellow, orange, red, purple, green, red, yellow, green, purple, purple, orange, yellow, purple, red, green, green, red, purple, orange, yellow, red

**Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials.

3.)  Calculate the experimental probability of each color. Write the experimental probability as a fraction, decimal, and percent.

Color / Experimental Probability
(fraction) / Experimental Probability
(decimal) / Experimental Probability
(percent)
Red
Orange
Purple
Yellow
Green

4.)  Make a bar graph of your experimental probability outcomes.

5.)  Write five sentences comparing the theoretical probability to the experimental probability.
