What are the chances? 6 consecutive numbers when 6 balls are picked from a set of 50 balls? Ref: https://www.nationallottery.co.za/about/how-to-powerball

(Actually, the 6th ball - the "powerball" is picked from a set of 20 just to complicate things)

My rough estimate is: 1/2 * 10/49 * 4/48 * 3/47 * 2/46 * 1/20 = 1 in 3,390,016
