On average it will take 70.15384615 balls to get any 12-mark pattern (not counting the free square), like the champagne glass, on a single card.

Please note that you can find the probabilities for covering any pattern by just counting the number of marks required and using the tables in my More Bingo Probabilities page.

For more bingo probability tables, please see my Probabilities in Bingo II page.

Another good source on bingo probabilities is Durango Bill's Bingo Probabilities. He has the same probabilities I do but goes into more depth on how they were calculated.
