Carmine surveys 40 7th graders at North to find out what their favorite gaming system is. 25 of those 40 students chose Nintendo Switch. If there are 240 7th graders at North, how many would you expect to chose Nintendo Switch as their favorite gaming system?

150 Students

Step-by-step explanation:

Carmine surveys 40 7th graders at North to find out what their favorite gaming system is.

25 of those 40 students chose Nintendo Switch.

In experimental probability, the relative frequency of an event is defined as the number of successful outcome of the event during experimental trials, divided by the total number of trials conducted.

Therefore:

The Relative Frequency of a Student Choosing Nintendo Switch =

If there are 240 7th graders at North,

Expected Number of Students = Relative Frequency X Total Number

                                               =0.625 X 240

                                               =150 Students
