The numbers 1,2,…,17 are divided into 5 disjoint sets. One set has 5 elements, one set has 4 elements, two sets have 3 elements and the last set contains the 2 remaining elements. Two players each choose a number from 1 to 17 at random. The probability they choose numbers from the same set can be expressed as a/b, where a and b are coprime positive integers. What is the value of a+b?

1. Hmmm. For each set of size n, there's a n/17 chance that each person picked a number from that set.

(5/17)^2 + (4/17)^2 + 2(3/17)^2 + (2/17)^2 = 63/289

Set S contains the elements = { 1, 2, 3, 4, 5, 6, 7, 8}. From this set, John takes sets of 6-digits each and sums all the possible 6-digit numbers that can be formed with those sets. What is the HCF of all these sums?
