I've had a couple of questions about how our promotional drawings work. Donald wanted to know if we used a flock of geese. Good suggestion, but we're slightly more scientific. Ms. Sugar had a few other points.
I just wanted to write in and say that I don't agree with the way the promotions are drawn. I read where they pull a certain % from email entries and a certain% from mail or drop off entries to go in the final draw. I think it should be entry for entry. Some people may enter 30 - 50 $10 entries by mail and not be chosen for the final drawing while someone else might just mail in or drop off 3 or 4 entries and make it in for the final drawing.
What she is describing is the miracle of random drawings. Every entry has exactly the same chance of winning. Someone who enters several times has better odds of being selected, but the person who just sends one can still be a winner. Isn't that great?
In our most recent drawing for the "Holiday in Hawaii" promotion, there were more than 159,000 entries. That's a lot. The mail entries alone fill seven 55 gallon drums. For reference, if a player had 100 entries, one of every 1600 would be theirs, but the chances of being selected are still less than one percent. As you can imagine, that's an awful lot of entries to handle in a single drawing, so here's what we do to make it manageable and keep it fair for everyone.
We conduct a pre-drawing to cut the room full of entries down to a manageable percentage. For that drawing, we select a number from both the mail-in/drop-off and My Lottery entries proportional to the number of entered through each method. We do this so that no matter which way players choose to enter, the final drawing accurately represents the overall population of entries. For instance, in the last drawing, 73 percent of the total entries were made online through My Lottery. So we drew a percentage of those entries and combined them with a percentage of the mail entries so that our actual drawing had a similar percentage of overall entries - 73 percent online, 27 percent mail entries. We then take that group of entries from the pre-drawing (and make physical envelopes for the online percentage) and combine them in a mixing drum. A blindfolded employee selects the winners. Through the entire process, each entry has the exact same odds of being selected as a winner.
