Given a set of 6 digits, how many combinations can be generated? I have 6 digits (e g: 1,2,3,4,5,6), then I use these digits to form a sequence of six digit pairs Each digit in the given set can be used twice, and only two different digits can be formed into a pair
combinatorics - How many combinations of 6 items are possible . . . With 1 item there are 6 possibilities with 2 you only have 5 choices after the first if you don’t repeat the same item So for 6 items the equation is as follows 6*5*4*3*2= 720 possible combinations of 6 items
How many group combinations of 3 can I make of 6 people? Great algorithm! This also works when you want to make groups of 3, in which case the first group you will have (52) (5 2) combinations to choose from, while the second group will have (22) (2 2), totaling 10 combinations in all
combinatorics - For a 6-character number, how many different numbers . . . 0 I have always been curious about this as an aviation enthusiast Using hexadecimal numbers 000000-ffffff, how many different numbers are there in this range including the first and last numbers? Would I be wrong to think the result would be 16x16x16x16x16x16 for all the permutations?
How many 6 digits number can be generated using digits 0-9 with . . . work out how many numbers 100000 to 999999 there are without repetition - first off, it starts with a digit from 1 - 9, then you choose 5 digits from 0 - 9 (excluding digit 1 that was chosen) so that is 5 from 9 - then jumbled 5! ways - then you subtract this from count of all numbers 100000 to 999999 – Cato Sep 12, 2016 at 16:11
combinatorics - How many combinations in this 4 digit pin - Mathematics . . . There are 10 possible numbers for the first digit, and then you can’t use that number again, so 9 for the second, and using the same logic, 8 for the third and 7 for the fourth That means there’s 10 × 9 × 8 × 7 = 5040 10 × 9 × 8 × 7 = 5040 combinations Divide this by the number of ways to order each one, 24, and you get 210, as you
Calculating license plate combinations - Mathematics Stack Exchange If there are 26 26 available capital letters and 6 6 available numbers 0 0 to 9 9 to complete a 6 6 "digit" combination (a license plate for example) what is the formula for calculating the number of possible combinations?
Number of possible combinations of x numbers that sum to y 19 I want to find out the number of possible combinations of x numbers that sum to y For example, I want to calculate all combination of 5 numbers, which their sum equals to 10 An asymptotic approixmation is also useful This question seems to be very close to number partitioning, with the difference that a number can be 0 See:
