There are 9 choices for the first digit, 8 for the second, 7 for the third, and 6 for the last.
So there are 9x8x7x6=3024 "permutations"
That means the order does matter.
If the order does not matter, divide that number by 4!=4x3x2x1
9C4 is 126
If you only want to change it into a percent, then all you have to do is move the decimal point to the right and put a line over the repeating numbers. Ex. .898989898989898989... is 89.89 % with the last 89 having a line over it
Oh, dude, you're making me do math now? Alright, so if you have three numbers and you're asking how many combinations you can make with those three numbers, it's like a little math puzzle. Each number can be used multiple times, so it's like a little party for those numbers. The total number of combinations you can make with three numbers is 27. That's like having 27 different outfits to choose from for a night out, but with numbers.
It depends on how many values each number is capable of having, and if repetition is allowed, and then if order is important. For example, are you rolling dice, picking Lotto balls, BINGO, etc. I am posting a link to a site called MathsIsFun, which has some good information about Combinations and Permutations.
There are 360 possible combinations.Where n = how many numbers are available to choose from and r = the number chosen each time then:Number of permutations = n! / (n - r)!= 6! / (6 - 4)!= (1 * 2 * 3 * 4 * 5 * 6) / (6 - 4)!= 720 / 2! = 720 / (1 * 2) = 720 / 2 = 360.(Note: this formula only applies where the order of the numbers is important and repetition is NOT allowed.)

Decimal numbers that never end but that end up having a repeating pattern are called recurring decimals or repeating decimals.Examples would be 1/3 = 0.33333333...or 452/555 = 0.8144144144144144... (where 144 is the repeating pattern).Reaching that repeating pattern is known as becoming periodic. Only rational numbers will have a repeating pattern. (The repeating pattern may be 00000, as in 4/2 = 2.00000... .)If a decimal number continues forever without having a repeating pattern, then it is a irrational number. One example of a number that continues forever without repeating would be π (pi) which continues infinitely without repeating.Pi is also referred to as a transcendental number.

To show very large or very small numbers, without writing out all the digits. To make it easy to compare such numbers, without having to count all the digits.
a constant pattern

Try some random numbers and letters until you have one

Having a good hypothesis, having statistics to work with, thinking about anamolous results, repeating experiments etc
