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.

How do you derive the mean deviation about the mean of the pareto type 1 distributions?
Easy.
The mean deviation about the mean, for any distribution, MUST be 0.
What the z-score of a person with a raw score of 20?
There is not enough information to answer your question. To determine a Z-Score, the mean and standard deviation is also required.
Why is the number 12 not matter but 12 marbles are matter?
because 12 is a number and marbles are things which is matter.
* * * * *
In much the same way as your thought about a marble is not matter - it is simply a concept in your mind. But a marble is matter.
What is the probability of getting a 2 3 or 12 on two dice?
Total number of possibilities on two dice = 36.
Number of ways to get 2, 3, or 12 = 4.
1, 1
1, 2
2, 1
6, 6
Probability = 4/36 = 1 chance in 9 = 0.111 = 11.1%
Chances=50% because on a 6 sided dice, as you have said, the sides are numbered 1,2,3,4,5 and 6. There are 3 even numbers and 3 odd numbers. Chances would be 3/6=50%
Where can i find a real-life application of a quadratic function?
Quadratic functions are used to describe free fall.
An imprecation is a curse. To imprecate is to call a curse upon someone or something.
What is the difference between probability distribution functions and probability density functions?
Probability density function (PDF) of a continuous random variable is a function
that describes the relative likelihood for this random variable to occur
at a point in the observation space.
The PDF is the derivative of the probability distribution (also known as
cummulative distriubution function (CDF)) which described the enitre range of values
(distrubition) a continuous random variable takes in a domain.
The CDF is used to determine the probability a continuous random variable occurs any (measurable) subset of that range.
This is performed by integrating the PDF over some range (i.e., taking the area under of CDF curve between two values).
NOTE: Over the entire domain the total area under the CDF curve is equal to 1.
NOTE: A continuous random variable can take on an infinite number of values. The probability that it will equal a specific value is always zero.
eg. Example of CDF of a normal distribution:
If test scores are normal distributed with mean 100 and standard deviation 10. The probability
a score is between 90 and 110 is:
P( 90 < X < 110 ) = P( X < 110 ) - P( X < 90 )
= 0.84 - 0.16 = 0.68.
ie. AProximately 68%.

How many 36's can you roll with two dice?
None.
Two ordinary dice can only sum to 12 and so you cannot roll a 36.
What are the odds of hitting 2 straits in a row at 5 card stud?
The odds of hitting 2 straights in a row at 5 card stud is about 5%.
Since the deck is reshuffled between deals, the two hands are sequentially unrelated, so the odds of two deals with two straights is simply th odds of one times the odds of another.
In order to draw a straight, you need to draw an ace, 2, 3, 4, 5, or a 10, jack, queen, king, ace, assuming that ace can be high or low.
The odds of drawing one of these cards is 10 in 13, but you have 5 chances to do so, so the odds of drawing the first card is 50 in 13.
The odds of drawing the second card is 39 in 51, but you have 4 chances to do so, so the odds of drawing the second card is 156 in 51.
Similarly, the odds of drawing the third, fourth, and fifith card is 38 in 50, 37 in 49, and 36 in 48.
Multiply these odds and you get 19,740,240 in 77,968,800. Reducing that to lowest terms, you get 246,753 in 1,112,110, which is the odds of drawing a straight. The numeric value of the odds is 0.22187823146990855221156180593646, or about 22%
Square that and you get 60,887,043,009 in 1,236,788,652,100. That is aready in lowest terms, so that is the odds of drawing two sequential straights. The numeric value of the odds is 0.049229949600214317813758989938262, or about 5%.
I assume you mean how many possible outcomes when looking at all 13 results.
It would be 2^13 = 8192
Is selecting 3 marbles at the same time independent or dependent event?
The second and third marbles depend upon the first, so they are dependent. Even if they are all being drawn together, because there is no replacement, each removal affects the original group of marbles.
How many ways can a combined 4 be rolled with two standard dice?
Assuming you mean a sum of 4, there are three ways this can be done: (1, 3), (2, 2) and (3, 1).
How many was can 4 people sit in a row of 4 seats if two of them insist on sitting together?
they sit on top of eachover
and the 3rd guy gives the 1st guy a reach-around
and the 2nd guy gives the 3rd guy a blowjob
and the 4th guy videos it and puts it on youporn.
hope that helped.
The frequency can be determined by recording the sum for each toss and producing a tally chart for the outcomes.
well lets look at the probability on your first pick you will get a blue eyed girl
2 have blue out of 5, so yo uhave a 2/5 chance, or 40%
on your second pick, there are 4 girls left, and one of them will have blue eyes now
1 have blue out of 4, so 1/4 or 25%
so you multiply the two probabilities to get your final sequential probability
2/5 * 1/4
find a common denominattor, for this we will use 20
8/20 * 5/20 = 40/400
simplify it you get 1/10 0.10, or 10% chance
Yes and no. Kidney stones feel as big as a marble. But if you swallow a marble it will come out a different way
