120 groups <span>(10*9*8/3*2*1=120) </span>of 3 (k) operators are possible to make from the 10 (n) qualified employees. This problem can be solved using the combination formula in mathematics which is to find the possible number of combination (group of operator) from a set of choices. (Formula : n*(n-1)*...* (n-k+1)/ k!).
