A part of a promotion, students who participate in a survey are mailed a free pass for one of three activities: movies, roller skating, or bowling. Participants have an equal chance of receiving each type of pass. If 900 students participate, how many would be expected to receive a pass for roller skating?

Question

A. 2 thirds

B.600

C. 450

D. 300

Answer 1

B. 600

Since participants have an equal chance of receiving each type of pass, the number of students expected to receive a pass for roller skating would be 1/3 of the total number of participants. Therefore, 1/3 of 900 is 300, so 300 students would be expected to receive a pass for roller skating.

Answer 2

are you sure?

Answer 3

I apologize for the mistake in my previous response. Let's correct the calculation.

If participants have an equal chance of receiving each type of pass, then 1/3 of the participants would receive a pass for roller skating.

1/3 of 900 is: (1/3) * 900 = 300

Therefore, the correct answer is:

D. 300
