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 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.

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 of rolling a specific d20 number arrangement in a single roll?
The probability of rolling a specific arrangement of numbers on a 20-sided die in a single roll is 1 in 20 to the power of the number of dice rolled.
If two dice are rolled one at a time what is the probability of getting a 1 followed by a 2?

10 coins are tossed once .The probalilty of getting exactly eight heads is?
The probability of getting 8 heads out of 10 tosses is (10C8)(1/2)^8 (1/2)^2 = 45 / 1024 = 0.0439. It is assumed that the probability of getting a head in a single toss is 1/2. 10C8 = 10 x 9 / 1 x 2 = 45
