10C5 = 10*9*8*7*6/(5*4*3*2*1) = 252
20C10 = 184,756
To have a median of ten with five numbers, the third number (when arranged in ascending order) must be 10. One possible set of five numbers could be 5, 8, 10, 12, and 15. This set is arranged in increasing order, and the middle number is indeed 10. Other combinations are possible as long as the third number remains 10.
The numbers are 10 and 5
Five of them.
The five on the left is ten times the five on the right.
