# Morning Discussion: Post-It From America

My American adventure is drawing to a close and I must say I'm going to miss you, young man. You're the progeny I shall never understand but you're alright in my book. We should see more of each other.

Having received a dose of the Virginia suburb experience, I would rather like to take similar jaunts to other parts of your mahoosive and diverse land. Downtown Salt Lake City, a tiny apartment in San Francisco, a bungalow in a one-stoplight Minnesota town, out in the New Mexico sticks... not chasing sights and attractions but simply enjoying a snifter of life. Take care, have fun, be good and don't be a stranger.

• so you have a small puzzle with 50 pieces. If you divide the puzzle among 10 people, giving them 5 pieces each, what are the chances they will have at least two pieces that connect?

• this is gonna be a tough combinatorics problem. You'd be better off writing a small program that enumerates all combinations and counts the ones that match you're requirements. Calculating it by hand is going to be difficult, though you're best approach is to find the number of ways no one has any matches and subtract that from 1.

Though reading what you're intent is I'd just go ahead and do it and see if it works.
