Experimental vs. Theoretical Probability Answers

Elisondra is eating at a restraurant with three friends. They want to choose at random who will order first. If you model the situation with the spinner, how many equal-sized sections should the spinner have?

Spin the spinner. Who orders first?

Cloudiness is predicted for 0.27✔ 2730270 days.

Sunshine is predicted for 0.360.40✔ 3640

The weather forecast for next season calls for a 10% chance of wind, a 20% chance of rain, a 30% chance of clouds, and a 40% chance of sunshine. If there are 90 days in the season, what is the predicted frequency for each type of weather?

Use the interactive spinner to model who among Elisondra and her three friends will order first. Then answer the questions.

What could be predicted if Elisondra and her friends use the spinner to decide who orders first during 40 visits? Check all that apply.

= 0.200.25✔ 0.350.50

The weather forecast for next season calls for a 10% chance of wind, a 20% chance of rain, a 30% chance of clouds, and a 40% chance of sunshine. If there are 90 days in the season, what is the predicted frequency for each type of weather?

Spin the spinner 90 times to simulate the 90-day weather forecast. Which type of weather has the lowest observed frequency?

The theoretical probability for rain is 1/5. The experimental probability for rain is 1/5✔ 1/6115.

Rain is predicted for 0.180.20✔ 1820 days.

The actual weather is exactly the same as✔ approximately the same as the opposite of the theoretical probability.
