Okay, just wanted to report back on my 'gambling adventure' on my 21st anniversary while at the NCTM Regional Math Conference in Atlantic City. In my post, I believe I referenced the idea that I would put 21 dollars down on 21 at the roulette table.
And here is where I believe math teachers are at a disadvantage in gambling - we know the odds and we know they are not good...stacked against us. The odds of hitting 21 (i.e. single number) are 2.6%, though the pay out is 35-to-1. The odds of hitting a number in a column are 31.58%, but with only a 2-to-1 pay out. What to do, what to do....?!
Hah...no brainer for this math teacher who hates to lose money and can do some quick calculating. I went column. And won. And then walked with 42 dollars more than I started with.
I am not going to be able to pay off the house or my daughter's college tuition, but I am a winner. Cheap and a bad gambler, but a winner!
