There are two types of roulette wheels, one with a 0 and another with a 0 AND 00.In the first case, the probability will be 0.324 and in the second it will be 0.316, approx.
To find the probability of something happening orsomething else happening, you add together the probability of each happening, and then subtract the probability of both happening.For instance, the probability of rolling greater than 4 on a dice is 1/3. You could roll 5 or 6. The probability of rolling an even number is 1/2. You could roll 2, 4 or 6. The probability of rolling greater than 4 or an even number is 1/3 + 1/2 - 1/6 which = 2/3

The probability of both dice showing the same number is 1/6 and the probability of different numbers is 5/6.
In Yahtzee, the probability of rolling two pairs in a single roll of five dice is relatively low. To achieve two pairs, you need to roll two dice showing one number, two dice showing another number, and one die showing a different number. The exact probability can be calculated as follows: there are 6 options for the first pair, 5 options for the second pair, and 4 options for the single die, leading to a probability of about 4.75%.
The probability is 0.0198. The probability of that happening twice is 0.000393 Is this the odds of it happening twice with the same number?

Uncertainty is the uncertainness of any happening which may occur but probability is the ratio of which the happening will occur.The number of happening can also be included in the probability section but not in uncertainty.Both the words are roughly opposites of each other.

A number cube has six faces, so the probability of any one of them showing on a fair throw is 1 in 6, or about 0.1667.
0.5 in each case. The probability of both happening simultaneously is 1/4
The probability of both dice showing the same number is 1/6 and the probability of different numbers is 5/6.

That's one face out of six. So the probability is 1/6
These are all independent events. So the probability of them all happening is the product of the probabilities of each one of them happening. The desired probability is (2/6)*(1/2)*(1/2)=1/12
In American Roulette, with 36 numbers, Zero, and Double Zero, the odds of winning a straight bet (a single number) is 1 in 38, or about 0.02632. The payoff, however, is only 35 to 1. In European Roulette, with 36 numbers and Zero, the odds of winning a straight bet is 1 in 37, or about 0.02703.
