I am confused by Statement 1 - Am I not reading enough into that statement properly.
Thanks!
mcm2112 What are you confused about?
Question says there are total of 25 students. A Group has to be made of 'n' from these 25 students.
Now before we go to first statement. If 'n' students have to be selected from 25 students, how many different combinations of 'n' students can be made? The answer is \(25C_n\)
Now coming back to statement 1. Statement 1 says that the value of n is such that the value of\(25C_n\) is the maximum.
So lets says if we says n=1,then \(25C_1\) = 25; If n=2, then \(25C_2\) = 25*12. Likewise this will continue till n=25.
So what u need to find out is for which value of n is \(25C_n\) is the maximum.
Hope this helps.
