Betting 2 dozens, and 2 columns simultaneously on a european roulette wheel (covering 32 numbers) what is the probability that this combination will not have hit atleast as much as expected after 20,50,100 or 200 spins?
And how far under expected hits when this happens?
What are the extremes?

My maths abiliy is fairly basic so I do not know how to go about working this out- maybe it is something that needs to be run on a sim?
Any help with this would be much appreciated!

For example
What is the probability that the 5 numbers not covered would hit 10 times in 37 spins?

combin(37,10)*(5/37)^10*(32/37)^27 = 0.014037078
It's not whether you win or lose; it's whether or not you had a good bet.
