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 are the chances of drawing four aces in a row from a shuffled deck of cards?
(4/52) (3/51) (2/50) (1/49) = 24/6497400 = 1/270725 ~= 0.000003694
16 out of 52

When two dice are rolled find the probability of getting a sum of 10?
There is an approximately 8% chance of that, or 1 out of 12.
What is a possible outcome of an experiment rolling an eight or picking 3dice from a jar?
Both rolling and eight or picking three dice from a jar could be possible outcomes of an experiment.
What is the Probability of rolling a 6 with 2 six sided die?
Im not sure what u are asking the probability of getting 2 sixes on both dice is1/36 the probability of getting a six on either dice is 1/6 and the probability of getting one six on both of the dice is 5/36 i believe hope i answered ur question
How many socks do you need to pull out of a drawer in the dark to get a matching pair?
If there's only 2 different kinds then you pull out 3 to get a matching pair.
Drawing a 7 from a deck of cards?
The probability of drawing a seven from a standard 52 card deck is 4 in 52, or 1 in 13, or about 0.07692.
Player 1 is holding 5 cards, Player 2 is dealt five cards from the same deck. Probabilities are:
1.card of player two matches one of the five cards of player 1: 15/47
2.card...:12/46
3.card...:9/45
4.card...:6/44
5.card...:3/43
->Probability of 2 players having the same cards is all probabilities multiplied:
81/511313 or 0.000158416!

The probability is 1/6 and can be solved a follows:
- There are 3! or 6 ways to line up the people: OMY, OYM, MOY, MYO, YOM, YMO.
- There is only 1 way to line them up as is described: OMY.
- Probability is number of ways it can occur divided by the total number of outcomes.
- Therefore the probability is 1/6 or .1667 or 16.67%.
What is the probability of a mother's first three kids being boys?
It is not possible to give a proper answer to the question because the children's are not independent. Among other things they depend on the parents' genetics and their age and there is no information on either of those factors. Also, the probability of a male child is not 0.5 as it is often naively assumed to be. It is, in fat, around 0.52.
However, if you suspend reality and assume that
- the children's genders are independent and
- the probability of a boy is 1/2
then the answer is (1/2)3 = 1/8.
The outcome of you rolling a 3 is 1 to 6. This is also equal to about 16%.
What's the probability to get black jack?
A Black Jack is an Ace and a face card (Ten through King). The probability of drawing a Black Jack as the first two cards from a standard deck is 4 in 52 times 16 in 51, which is 0.0241 (Ace First), or 16 in 52 times 4 in 51, which is also 0.0241 (Ace Second).
Since time is a continuous variable, the answer is that the song must be sung infinitely many times.
Time might be a continuous variable, but recorded time is not.
11/4165 = 0.002641056... ≈ 0.26%
There are 13 hearts in a deck of 52 cards.
So when dealing 4 cards, the probability of all 4 to turn out to be hearts is:
P(4 hearts in 4 cards) = (13/52)∙(12/51)∙(11/50)∙(10/49) = 0.002641056...
≈ 0.26%
An event can either happen or not happen. If the probability of it happening is 3/5,
then the probability of it not happening is 2/5.
2 white counters and 1 black counter What is the probability that the counter will be black?
1/2
Because there is 2 white counter and 1 black and there is a chance you will get white.
But a probability getting white is that there is 2 white counters.

How many questions can you miss to get an 83 on a 150 question test?
100 - 83 = 17
17/100 x 150 = 25.5 missed
with rounding you could miss 25 or 26
What is the define of probability?
the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases possible
How do you calculation joint probability?
You have a function with two arguments (inputs). After that, the calculations depend on whether or not the two random variables are independent. If they are then the joint distribution is simple the product of the individual distribution. But if not, you have some serious mathematics ahead of you!
