Question

Stillwater Junior High divides students into teams taught by a group of teachers. The table shows the number of students in each team.

Team Number of students
Acers 78
Blazers 80
Outbacks 83
Quasars 77
Voyagers 82
Total 400
The principal uses a computer to randomly select the name of a student from all the students in the school. With the computer program, it is possible to draw the name of the same student twice. If the principal selects the name of a student from the Acers on the first try, what is the probability she will draw the name of another student from the Acers on the second try?

Answer 1

[AI-generated answer — Bot GPT 3.5]

The probability of selecting a student from the Acers on the first try is 78/400 = 0.195.

Since the computer program allows for the same student to be selected twice, the total number of students in the school remains 400 even after the first selection.

Since the principal already selected one student from the Acers on the first try, there are now only 77 students left in the Acers.

Therefore, the probability of selecting another student from the Acers on the second try is 77/400 = 0.1925.

So, the probability she will draw the name of another student from the Acers on the second try is 0.1925.
