Hi guys,

I am studying for an math test and there was a question about the probability of roulette.

What is the chance that a dozen does not fall for 17times given that that same dozen has not fallen for 10 times.

Is it just P10 multiplied by P17 divided by P10 . Or what am i missing?

Thanks a lot.

Bob
