Since participants have an equal chance of receiving each type of pass, we can divide the total number of participants (900) by the number of activities (3) to find the expected number of participants receiving a pass for roller skating.
900 / 3 = 300
Therefore, we would expect 300 students to receive a pass for roller skating.
So, the answer is 300.
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?(1 point)
