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 probability of a king from a standard deck of playing card?
The answer depends on how many cards are picked. If it is only one random card, then the answer is 1/13.
How many ways can the letters in the world be rearranged?
I would say like a billion or a trillion. lol
What is the probability of getting a 2 on a dice?
1/6
A dice has six faces. And '2' is on one if its faces. So the probability of getting a 2 on a dice is 1 over 6.
What if probable cause didn't exist?
Then an arrest might not be made, and a prosecution could not be conducted.
How many 9 digit combinations are there for the numbers 1 through 80?
There are 9 slots, if you will, to place numbers. If they can't be used more than once, the answer is 80*79*78*77*76*75*74*73*72. If they can be used more than once, each slot has 80 so that answer would be 809.

If you assume a binomial distribution, the variance is n*p*(1-p) where
n is the number of voters = 30
p is the probability of support = 0.36
So variance = 30*0.36*0.64 = 6.912
Is there a formula for probability problems?
Yes. The sum of the probabilities of all possible outcomes is equal to one.
Given events that are equally likely to happen, the probability that any given outcome occurs will be equal to the number of specified outcomes, divided by the number of all outcomes.
If events are not equally likely to happen - let's say that Bent-Nose Bill is holding a lottery - then the probability is considerably different. As Damon Runyan put it, "The race is not always to the swift, nor the battle to the strong, but that's the way to bet"
That is the correct spelling of the adverb "probably" (likely, most possibly).
..... Well, this is really specific question....
In probability, a coin is usually referenced when talking about heads and tail.
A Deer, A Dog, A Cat, A Mouse, A Bear, A Cougar, A Mountain lion,.............These could go on for a while:)

How many ways can the letters in FACTOR be arranged so that the first and last letters are vowels?
48
What happens when two polygons have the same z value and the z-buffer algorithm is used?
the pixel intensity in final image will be of the surface last scanned if the z value is same.
To cut the maximum likely error in half the sample size should be?
... should be increased by a factor of 4. Note that this implies that the only errors are statistical (random) in nature; increasing the sample size won't improve systematic errors.
What does the word commutative property of addition mean?
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2. Any time they refer to the Commutative Property, they want you to move stuff around; any time a computation depends on moving stuff around, they want you to say that the computation uses the Commutative Property.
- Use the Commutative Property to restate "3×4×x" in at least two ways.
They want you to move stuff around, not simplify. In other words, the answer is not "12x"; the answer is any two of the following:
4 × 3 × x, 4 × x × 3, 3 × x × 4, x × 3 × 4, and x × 4 × 3
- Why is it true that 3(4x) = (4x)(3)?
Since all they did was move stuff around (they didn't regroup), this is true by the Commutative Property.
