Despite all of the discussion about probabilities and figures, it seems that few people can actually calculate mathematically the chance of any roulette result. Sometimes they resort to excel or utilize specialized applications, trying to test millions of spins in order to come up with the right number. When someone understands basic probability, one can answer just about any question regarding the certainty of any result using just a simple calculator or simply place the equation as a formula in a simple excel file.
First we must know what’s exactly the the factorial function, which gets the symbol:!
This means to multiply a series of descending natural amounts.
4! = 4 ?? 3 ?? two ?? 1 = 24 7! = 7 ?? 6 ?? 5 ?? 4 ?? 3 ?? 2 ?? 1 = 5040
1! = 1
0! =1 (axiomatically)
Practically for roulette functions, a factorial shows in how many various ways, different items (or amounts ) could be organized. Without repetitions of number or the exact same item. To give you an idea how enormous this number can become, for 37 amounts, like in European roulette:
37! = 1.3763753??1043
This means that there are lots of trillions of trillions of different arrangements of the 37 roulette numbers. Without counting the possible repetitions of amounts. Just how many distinct ways (sequences) all the roulette numbers can show up in 37 spins. You may read more about mathematical mixtures.
