In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

An estimation, like 600 divided by 6, will show you that the answer should be around 100, not 10 or 1000.
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.
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.
What is the probability of rolling a number greater than 27?
The answer depends on how many dice are rolled, whether or not they are fai, how the numbers thrown are combined. For example, in backgammon, a double allows you to move four times the value shown.

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
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.
