10 ! (To find the median add the two middle numbers 7,13 = 20 divide 20 by two and you get 10 as your median. Mode means the most common number which means the mode is also 10)
This is a combination problem.
The formula is n! / (r!(n-r)!
where n is the total number of people and r is the number of people to be picked.
n = 15, r = 4
15! / (4!(15-4)!)
15! / (4!*11!)
Total combinations = 1,365
