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 you arrange the letters in an eight letter word?
If all the letters of the word are different then the answer is 8! = 8*7*6* 5 *4*3*2*1 = 40320.
How did theoretical probability get its name?
The theoretical probability of an event is the probability that is calculated on theoretical considerations. This normally entails modelling the experiment and then employing the laws of science to determine the event space and the probabilities of the outcomes.
For example, suppose you wish to determine the theoretical probability of getting the number 5 when you roll a normal die. There are 6 possible outcomes. If the die is fair then each of these outcomes is equally likely. Therefore the probability of any particular number - for example, 5 - is 1/6.
What is the probability of flipping a coin twice and getting head on the first flip?
The probability is 1/2 because the second outcome has no affect on the first outcome.
Why is A bell shaped probability distribution curve is NOT necessarily a normal distribution?
There are infinitely many sets of parameters that will generate a bell shaped curves - or near approximations.
The Student's t or binomial, for large sample sizes get very close to the Gaussian distribution. There are others, too.
What is the probability of tossing three coins and having them exactly one of them show tails?
It is 0.375
It is 0.375

In 3 years Alex will be 3 times as old as his sister Precy (is now):
a+3 = 3p
a = 3p-3
A year ago Ales was 2 times as old as Precy (is now):
a-1 = 2p
a = 2p+1
3p-3 = 2p +1
3p = 2p +4
p = 4
Precy is 4
a = 2p + 1 or 3p - 3
a = 8 +1 or 12 - 3 = 9
Alex is 9
The probability of getting a six on a six sided die and then getting a tails?
The probability of getting a six on a six sided die and then getting a tails is zero. There is no tails on a die.
you could do roll 5 on one side with 3 on the other.Or 4 on one side and 4 on the other.Or you could roll 7 and a 1 or you could roll 6 on one side and 2 on the other.:)(:
.237 or about 24 %
What is the probability of answering 50 questions right out of 100?
Depends on the questions, and how they are answered. T/F, multiple choice, matching, essay, etc. Could be randomly answering, making educated guesses, or applying some amount of knowledge on the subject. Each of these impacts the probability of supplying correct answers.
If you keep rolling the die, then the probability of rolling a 6 and then a 1 on consecutive rolls is 1.The probability is 1/36 for the first two throws.
