There are 38 slots on a roulette wheel, two of them being "0" and "00", and the remainders being all numbers from one to thirty-six inclusive.
This means that your chances of getting any number from 1 to 12 are 12/38, or 6/19, which is is just a bit more than 31.5%

When do you have a geometric distribution?
A geometric distribution comes from a binary probability which does not have a set number of trials. It seeks to determine how many trials must be conducted before success is achieved. For example, instead of saying, "If I shoot the ball 5 times, what is my probability of success," a geometric probability would question, "How many times will I have to shoot the ball before I make a basket?"
6 balls in a bag The probability of taking a red ball out of the bag is 0.5 A red ball is taken out of the bag and put to one side What is the probability of taking another red ball out of the bag?
0.4
These bag contains 6 white ball 3 red balls and one blue ballif one ball is drawn from the bag what is the probability it will be white?
3/5 probability of a white ball being drawn.
A bag contain 4 green 6 black 7 white balls a ball is drawn at random what is the probability that it is a green or a black ball?
This is a law of addition probability which states that the probability of A or B equals the probability of A plus the probability of B minus the probability of A and B. Written in mathematical terms, the equation is: P(AorB) = P(A) + P(B) - P(AnB) where P(AnB) = 0 (since you can not pull out a green and black ball at the same time). Let P(A) = Probability of drawing the green ball & let P(B) = Probability of drawing the black ball. Total outcomes is 17. So, P(A) = 4/17 & P(B) = 6/17. Therefore P(green or black) = 4/17 + 6/17 = 10/17.
A box contains 75 balls numbered from 1 to 75 If 7 balls are drawn with replacement what is the probability that at least two of them have the same number?
25.1%The probability of having at least two same number balls when 7 balls are drawn withreplacement from a box containing 75 numbered balls from 1 to 75 is calculated asfollows:We calculate the probability of drawing 7 times a ball (with replacement) and havingall different numbers. Then we subtract this value from 1. This will be the probabilityof all the possibilities of combinations of 7 numbers where at least two are repeated.1.- For the 1st ball the options are 75/75.2.- For the 2nd ball the options for not repeating the 1st number are 74/75.3.- For the 3rd ball the options for not repeating the previous two numbers are 73/75.4.- For the 4th ball the options for not repeating the previous three numbers 72/75.5.- For the 5th ball ........................................................................... 71/75.6.- For the 6th ball ........................................................................... 70/75.7.- For the 7th ball ........................................................................... 69/75.The probability of drawing seven balls (with replacement) having all different numbersis: 75/75(74/75)(73/75)(72/75)(71/75)(70/75)(69/75) = 0.749419476...The probability of having at least two same number balls when 7 balls are drawn with replacement from the given box is:P = 1 - 0.749419476... = 0.250580524...≈ 25.1%

There are 38 numbers on a roulette wheel and I bet 12 of them. What is the probability of not hitting one of my numbers on 11 consecutive spins?
If the probability of an event will occur is p, then the probability that it will occur in n trials is pn.(That's p raised to the n power). So if you bet on 12 numbers, then (38-12=26) numbers are empty. The probability of the ball landing on one of these empty numbers is 26/38. So (26/38)^11 = 0.01538, which is about 1.538 % or a 1 in 65 chance.

So if you have a lucky game its always best to quit while you are ahead.
