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.

"statified sampling" is a way of getting an 'average' which represents the entire universe, or every thing that exists that somebody wants to count or measure. The entire universe is broken down into groups that dont overlap and a 'sample' is taken from each group. If it is done to the satifaction of statiticians, it can be as accurate, if not more because of the problems of counting and measuring everything, than a total count of measurments.
What is the probability of getting a number less than 7 on a standard six-sided die?
100%.
Hello, 6 sided die? There is no number greater than 6, therefore no 7. This is like a Kindergarten question.
What was the fifth suit added to a deck of cards?
There is no fifth suit. Just king, queen, jack, ace. there might be a fifth if the joker was allowed to be layed down in a game of cards.
What is the shortest way to figure out how many ways you can stack ten books on a shelf?
Use the factors of the number. Factors of 10 are... 1,2,5 & 10. Therefore they will stack either in 1 row of 10 books or 2 rows of 5.
It is approx 0.4388
However, I am not at all sure what you mean by "the condition ace with non uniform distribution". None of the relevant distributions are uniform so the condition seems to be totally irrelevant!
What major events occurred in 1985-1989?
World War two was happening and Martin Luther King Jr. gave his "I have a Dream speech"
On a number cube what is the probability of rolling a number less than 3?
2/6 = 1/3 = (33 and 1/3) percent
What happened on November 17 2008?
This was the date that Somali pirates captured the MV Sirius Star. It is also the date that the global crisis of 2008 started. The Russian stock exchanged collapsed.
The humerus is a bone big bone in the leg, going from the hip to the knee. It is what the thigh muscles cling to as they propel the legs during movement.
What are chances of pulling 4 aces out 52 cards?
[original answer] four in 52!
====
The question is not fully stated, but I assume what is being asked is "What are the chances of pulling all four aces out of 52 cards when four cards are drawn".
The answer is 1 / 270725 = 0.00000369 = 0.000369%. Approximately four out of one million.
The chances are (4*3*2*1) / (52*51*50*49) = 24 / 649700 = 1 / 270725. That is, on the first draw there is a 4/52 chance of drawing one of the four aces out of the full pack; In the 48 out of 52 cases where an ace isn't drawn, "you lose".
In the 4/52 cases where an ace is drawn first, there is a 3/51 chance of drawing one of the remaining three aces from the remaining 51 cards. If that happens, there is a 2/50 chance of drawing one of the remaining two aces from the remaining 50 cards; and then a 1/49 chance of drawing the last ace out of the remaining 49 cards.
[ If the question is "What are the chances of pulling any of the aces out of 52 cards in one draw" then "four in 52" is correct. ]
Would the mean and standard deviation be negative if the set has only negative values?
The mean would be negative, but standard deviation is always positive.
Which event occur last in the series of events recounted in a Sperate Peace?
the narrator revisits the tree by the river
The train can be either early, on time or late.
The total probability must be 1. Thus:
pr(early) + pr(on_time) + pr(late) = 1
0.09 + pr(on_time) + 0.4 = 1
=> pr(on_time) = 1 - 0.4 - 0.09
= 0.51
Probability of being on time is 0.51
What is the propability of drawing a heart from a deck of 52 cards?
The answer depends on how many cards are drawn, whether or not at random, from an ordinary deck of cards, with or without replacement. The probability for a single card, drawn at random, from a normal deck of playing cards is 1/4.
What if your z score computed wrong in spss?
You then have big problems. However, rather than SPSS making incorrect computation, it is more likely that the model is wrongly specified.
How is experimental probability different from theoretical probability?
The two differ in the manner in which they are derived. The first requires a large number of trials (or simulations) whereas the second requires a suitable model to which the laws of science - physics, genetics - can be applied.

What is the difference between population and sample in statistics?
A population includes all members of a defined group. A sample, on the other hand, is just a part of the population.
What are the odds of selecting a 3 from a deck of cards?
Well there are 52 cards in a full deck. There are four 3's in a full deck, so the probilitiy of selecting of 3 out of a deck would be 4/52..
so the odds are 1 out of 13 OR 7.69%
What is the probability of rolling a 9 with two dice?
The probability of rolling a 9 with two dice is 4/36 or 1/9. There are 36 possible combinations and a 9 is obtained by rolls of 3,6; 4,5; 6,3; & 5,4.
What is the Chance of NOT Drawing an Ace?
The probability of not drawing an Ace from a standard deck of 52 card is 48 in 52 or 12 in 13, or about 0.9231.
If steven rolls two dice what is the probability that the dice totals 7 or 11?
Assuming Steven is rolling 6-sided dice...
First, determine how many combinations will equal 7 or 11:
1,6
2,5
3,4
4,3
5,2
6,1
5,6
6,5
8 possible answers
Now, determine how many possible combinations there are in total:
6 possibilities for each die
6*6 = 36 total permutations
The probability of a 7 or 11 is therefore 8/36, 2/9, or 22.2%
