If a single die is rolled 9 times what is the probability of getting exactly 2 sixes?

There are 69 total possibilities.
Imagine having nine boxes, that each hold how many possibilities each individual dice can hold. Any two of the dice can only be a six, therefore any two of the boxes can only have a 1 (only one possibility). The rest of the boxes can be anything, other than 6 (so the rest of the boxes have 5 possibilities each).
[1] [1] [5] [5] [5] [5] [5] [5] [5]
Now multiply all the possibilities together you get total number of combinations. In this case, it's 57. You can use this same strategy to see why the total number of possibilities is 69.
The answer is total restricted combinations divided by total combinations.
57 / 69 ~= 0.007752 (or roughly 0.78%)

What is the probability of rolling a dice and getting an odd number?
The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.The probability of getting an odd number in a single throw of a fair die (not dice!) is 1/2.
What is the probability of rolling 2 sixes in a row with a single die?
It is a certainty. If the die is rolled often enough, the probability that two consecutive rolls show a six is 1.
A single die is rolled one time Find the probability of rolling a number that is odd and less than 4?
1
What is the probability of getting a 7 after rolling a single die numbered 1 to 6?
The probability of rolling a 7 at any time on a single die is zero.
What is the probability of rolling a multiple of 3?
The answer depends on how often the die is rolled. As the number of rolls increases, the probability gets near enough to 1 as makes no difference. For a single roll, the answer is 1/3.
A single fair die is rolled find the probability of getting a 1?
It is 1/6.
When a single die is rolled what is the probabiltiy of getting a 9?
With a standard 1-6 die, the probability is 0.
What is the probability that when a fair 6 sided die is rolled a prime number faces up?
On a single roll, the probability is 1/2.
What is the probability of rolling a dice and getting an odd number?

What is the probability of rolling a number that is divisible by two on a six sided die?
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
What is the probability of a single number on a 6-sided die rolled 84 times?
-78
A single die is rolled what is the probability tha the number rolled will be greater than 3?
Total different outcomes = 6Successful outcomes = 3 (rolls of 4, 5, or 6)Probability of success = 3/6 = 1/2 = 50%
What is the probability of rolling 2 sixes in a row with a single die?
It is a certainty. If the die is rolled often enough, the probability that two consecutive rolls show a six is 1.
If two dice are rolled one at a time what is the probability of getting a 1 followed by a 2?
there are 36 possible combinations in two single die tosses. The odds of any one combination is then 1:36
10 coins are tossed once .The probalilty of getting exactly eight heads is?
The probability of getting exactly eight heads when tossing 10 coins once can be found using the binomial probability formula. Assuming a fair coin, the probability of getting a heads is 1/2. Plugging in the numbers, the probability of getting exactly eight heads is (10 choose 8) * (1/2)^8 * (1/2)^2 = 45/1024, which is approximately 0.04395.

What is the probability of getting a 0 after rolling a single die nmbered 1 to 6?
Since zero is not on the die, the probability of getting a zero is 0%.
