A simple random sample (or SRS) in statistics is a subset of individuals (a sample) chosen at random from a larger set (a population) with the same probability.
It is the process of selecting a sample at random.
In SRS, each subset of k people has the same chance of being chosen for the sample as any other subset of k people.

To find how many students in the entire 225-person class would be expected to prefer having the Fall Festival in October:

Total Strength of the class = 225
f the 90 students surveyed, 25.6% preferred October.
So, it can be assumed that 25.6% of the entire 225-person class would prefer having the Fall Festival in October
So, nos. of students = 225 × 25.6/100 = 1/4 of 224 = 56
Roughly 60 students would prefer having the Fall Festival in October.

Therefore, approximately (B) 60 students would prefer the Fall Festival to be held in October.
