Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What is the total number of outcomes when rolling two number cubes and tossing one coin?
The total number is 6*6*2 = 72 outcomes.
What does probalility distribution mean?
In parametric statistical analysis we always have some probability distributions such as Normal, Binomial, Poisson uniform etc.
In statistics we always work with data. So Probability distribution means "from which distribution the data are?
How many times would you have to roll one die to roll a six five times?
If you were really unlucky, infinitely many times! The probability of that happening is very tiny but it is not zero.
it is 5
40,320 without taking into account repeated letters (so a bit less) but I'm no mathematician so I can only give you the first step.
It is 2/13.
How do you convert variance of 10.8 square inches into standard deviation?
Standard deviation = square root of variance.
What is the probability that you will pull an odd heart from a deck of cards?
4/52 then is reduces to 2/26 then down to 1/13.
How do you know if 4.1 is a valid probability?
4.1 is not a valid probability because probability can never be greater than 1.
What is the probability of rolling a 3 with a pair of dice?
On a standard pair of six-sided dice, there are two ways to roll a "3"; i.e., a "1" and a "2" or a "2" and a "1". There are 36 possible outcomes. Therefore, the probability of rolling exactly 3 is 2/36, which equals 1/18.
The probability of rolling 3 or higher is 35/36. The probability of rolling 3 or lower is 3/36, which is 1/12.
What is the probability of rolling an even with one roll of a numbers cube.
Compute the probability of rolling seven with two six sided dice?
Each die has 6 outcomes: 1, 2, 3, 4, 5, 6. Total outcomes for 2 die is 6 * 6 = 36. You can easily write out the 36 outcomes; but the ones that add to 7 are: 1&6, 2&5, 3&4, 4&3, 5&2, and 6&1. Therefore, there are 6 ways to get a 7. So, 6 ways to get a 7: = 6/36 = 1/6.
How can one have identical twins?
There are two primary types of twins, Identical and Fraternal.
Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins.
Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
Does the King of Diamonds represents a real king?

Whether or not this is actually true reamins to be verified.

Assuming you are dealing with a standard cubic die, the probability is 1/36.
What is the probability that a random 2 digit number ia a multiple of 7?
There are (99 - 9) = 90 2-digit numbers.
13 of them are multiples of 7.
