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 many different ways can the letter WRITTEN be arranged?
7!/2! = 7*6*5*4*3 = 2520
7!/2! = 7*6*5*4*3 = 2520
7!/2! = 7*6*5*4*3 = 2520
7!/2! = 7*6*5*4*3 = 2520
What is the probability that a randomly chosen letter is a vowel?
5/24, or five out of twenty four, or with numbers, five out of infinity
Why do so many people gamble and the probability of winning is very low?
People often look at the expected value of the outcome rather than only the winning probability. So with bigger prizes, the probability of winning can be lower and still remain attractive.
Many people experience a buzz out of gambling and it can be very addictive.
Also, there are some games where the probability of winning can be increased - legally. A good poker player, for example can expect to win at a table full of less expert players.
How many black 10's are in a standard deck of cards?
There are two. The 10 of clubs and the 10 of spades.
Why does the standard deviation weight extreme deviations more than does the arithmetic mean?
Because the standard deviation is based on the square root of the sum of the squares of the deviations, and, as a result, the sum of the squares of the deviations puts more weight in outliers than does a simple arithmetic mean.
Note: I wrote this and then had second thoughts, but I'm keeping it in so that someone with more knowledge can weigh in (pun intended). I'm not certain how the arithmetic mean factors into the question. I think the questioner, and definitely this answerer, is confused.
What is the probability of flipping 6 fair coins 1 time and getting all heads?
0.015625
For each coin, the probability of it coming up heads is 0.5. For six coins you multiply 0.5 by itself six times, which is 0.5 to the power of 6. This comes out to 0.015625, or about 0.016.
If you work with fractions, then (1/2)^6 = 1/64, which comes out to the same decimal.
the probablility of drawing a nine or clubs from all four randomly shuffled decks with 52 cards is 1 out of 7,311,616
Explain how to find the absolute value of an integer?
The absolute value of an integer is found by ignoring its sign (plus or minus).
Probability of rolling a pair of dice and getting a total of 12?
to get a 12 you need to roll two a six on each of the two dices. the probability of rolling a six 1/6 on each, and to get six on two, is the 1/6 *1/6 = 1/36
As described, the deck contains 52 cards, numbered 1 to 13, four times in four colors, red, blue, black, and green. The probability of drawing more than one red card with the same number on it is zero.
What is the probability of selecting a ten or a king of fifty two card decks?
A standard 52 cards deck contains 4 kings and 4 tens. Given that the type of the card does not matter, we have a total of 8 valid cards (4 kings + 4 tens) to choose from a 52 cards deck. Hence the probability is 8/52.
What is probability of drawing a card other than ace?
The probability of drawing a card other than an Ace, in a standard deck of 52 cards, is 48 in 52, or 12 in 13, or about 0.923.
Remember: Probability is simply the number of expected events divided by the number of possible events. In this case, you can count the other events (48 in 52) or you can subtract the results of the negative events (4 in 52) from 1, i.e. 1-(4/52) or 1-(1/13) is still about 0.923.

Total combinations for drawing 5 cards is 52 choose 5 which is...52*51*50*49*48/(5*4*3*2*1)
possible outcomes for drawing 5 hearts is 13 choose 5 which is...13*12*11*10*9/(5*4*3*2*1)
Probability of drawing 5 hearts is (52 choose 5)/(13 choose 5) which is....000495
