Instead, suppose to win the grand prize of​ $1,000,000, you have the pick the same six numbers as the six b***s picked. Here order does NOT​ matter, so we are dealing with a COMBINATION of 6 b***s out of 40 b***s. Use the combination formula from class to determine the total number of possible outcomes. Then the probability of winning is 1 over this total number of outcomes.
