I expect to soon have fifteen names of AZ members to be entered in a raffle. I am thinking of numbering the names from 01 to 15 and then using the closing value of the Dow Jones average on December 1st and successive days to pick the winner. The first time the Dow Jones average ends in a number between 01 and 15, the AZ member with that number by their name wins the raffle. I really want to be sure I am using a fair and publicly viewable method to decide the raffle winner, so I am asking whether anyone sees a problem with the method outlined above. Thanks in advance for your thoughtful comments.
