At a middle school, 30% of students buy lunch in the cafeteria and the remaining students bring lunch from home. A spinner with 10 equal-sized sections numbered 0–9 will be used to simulate the lunch trend. Explain how to assign the numbers 0–9 to conduct the simulation. Use the drop-down menus to explain your answer.

We know that 30% of the students buy lunch in the cafeteria, and the other 70% bring their lunch from home.

We need to simulate this with a spinner with 10 sections labeled from 0 to 9.

We can assign 3 of the numbers of the spinner to the event "student buys lunch in the cafeteria"  

This is because we will have 3 outcomes out of the 10 in the spinner, then the probability is P = 0.3 or 30%, then it coincides with the probability above.

suppose that the numbers 0, 1 and 2 are for the event "student buys lunch in the cafeteria"

Then, you can put a marker around the spinner that is on top of a table, and then spin it, the number that ends in the marker represents the result of the experiment.

if the number is 0, 1 or 2, the student buys lunch in the cafeteria.

If the number is 3, 4, 5, 6, 7, 8 or 9, the student brings his/her lunch from home.

may i see the picture? it would a lot, xox
