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 drawing 3 black cards (spades or clubs) from a standard 52-card deck?
The probability of drawing three black cards from a standard pack depends on:
- whether the cards are drawn at random,
- whether or not the drawn cards are replaced before the next card is drawn,
- whether the probability that is required is that three black cards are drawn after however many draws, or that three black cards are drawn in a sequence at some stage - but not necessarily the first three, or that the first three cards cards that are drawn are black.
There is no information on any of these and so it is not possible to be certain about the answer.
The probability of drawing three black cards, in three random draws - without replacement - from a standard deck, is 0.1176 approx.
How do you make predictions using experimental probability?
Examples like the propability for raining tommorrow will 1/2 may or may not happen probability is called possibility
Which best describes how theretical probability is determined?
Theoretical probability is determined by using scientific principles to determine the mechanism through which the required event occurs.
It is 7/8.
It is 1/12.
Technical risk.

In the last 40 days Mr.Neptune's newspaper has been delivered late 6 times what is the probability?
Just dividing 6 and 40 and looking at the percentage that pops up, we could obviously see that it is unlikely that it will happen the next day. The percentage is 15% which is supposedly added in the unlikely section.
What is The probability of The next 7 births being girls?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.
However, if you assume that they are independent events then, the probability that the next seven births are girls (given that the global probability of a girl is 0.48), is 0.00614 approx.
How many unique ways are there to arrange the letters in the word APE?
six
each of the three first letters has the other two alternating
so 3 x 2 = 6

You need to calculate your mathematical expectation.For the winning case, your gain is: 0.624 x 1
For the losing case, your gain is: (1 - 0.624) x (-2)
(So, in each case, probability multiplied by the amount you would win/lose.)
Do the calculations, and add everything up. If the sum is positive, the game is in your favor.
26.5
It is 67%.
If you roll a number Cube twice what is the probability of rolling a even number than an odd number?
50 percent
In how many ways can 5 diamonds be drawn from a standard deck of 52 cards no replacement?
There are 1287 ways.
If 2 six-sided dice are tossed in how many ways can at least one of the dice come up a 3?
11 ways (out of 36, resulting in a probability of 11/36):1-3, 2-3, 3-3, 4-3, 5-3, 6-3, 3-1, 3-2, 3-4, 3-5, 3-6
What is the probability of being dealt 4 aces from a standard 52 card deck?
The probability, if the cards are dealt often enough, is 1.
On a single deal, the prob is 3.69379*10^-6
If it has similar characteristics as the population the sample is termed?
It is called a representative sample.
If the balls are selected at random, then the probability is 12/95.
