How to deal with really loose/big betting player?

"Statisics are only statistics...take craps for example . The dice each have 6 numbers 1 - 6. Let's use the 11 ( 65 ) . Statistically ( Mathematically ) the number eleven is supposed to show up every 16 times it is rolled. That is a true statement. So for every 16th roll I should bet on the 11. Bet 10 dollars and you win 150.00. Good for you and bad for the casino. Or is it? No because the casino knows that the dice could be rolled 100 times and the dice never show an eleven. Statistics show that every 16 rolls it should show up. So what happened? Well on roll 101 the dice rolled an 11, and then the next roll an 11 and then the next. and then three rolls later another 11. So statistically is is now catching up to the math."

On average 11 only comes up twice every 36 times, or once every 18 times.
