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 how can you design a simulation to guess whether the nest 20 students buy lunch or bring lunch from home?

Step-by-step explanation:

Given Data:

At a middle school,  30% of students buy lunch in the cafeteria

Let the number of students that bought food from the cafeteria be x = 30% = 0.3

The remaining students bring lunch from home.

Let the number of students that brought food from home be y = 1 - x

1 - 0.3 = 0.7

However;  a spinner with 10 equal sized sections is used; Then

The probability of x and y is  3 and 7 respectively.

That typically implies that:

For every three students that bought food from the cafeteria ; seven students brought food from home.

We are told that the spinner is numbered from 0-9:

So; we can attribute the side of the spinner for the simulation as follows:

Section 0 = y

Section 1 = y

Section 2 = x

Section 3 = y

Section 4 = y

Section 5 = x

Section 6 = y

Section 7 = y

Section 8 = x

Section 9 = y

The attributed section for x = 3 and the attributed section of y = 7

10
