If the numbers are all different, then 25C5 = 25*24*23*22*21/(5*4*3*2*1)
= 53,130.
To calculate the number of different combinations of 5 numbers chosen from 1 to 25 without repetition, we can use the formula for combinations: nCr = n! / r!(n-r)!. In this case, n = 25 (total numbers) and r = 5 (numbers chosen). Therefore, the number of combinations is 25! / (5!(25-5)!) = 53,130 different combinations.
Assuming you meant how many combinations can be formed by picking 8 numbers from 56 numbers, we have:(56 * 55 * 54 * 53 * 52 * 51 * 50 * 49)/8! = (7 * 11 * 3 * 53 * 13 * 51 * 25 * 7) = 1420494075 combinations. (Also equal to 57274321104000/40320)
If each number is different from all of the other numbers and the combinations are considered distinct unless they contain the same numbers in the same order, the answer is 25 X 24 X 23 X 22 X 21 = 6,375,600. If the combinations are distinct only if they do not contain the same numbers, irrespective of order, then the answer is (25 X 24 X 23 X 22 X 21)(5 x 4 x 3 x 2) = 53,130.
If the order of the five in the set makes a difference, there are (25 x 24 x 23 x 22 x 21) = 6,375,600 sets.If the order doesn't matter, then there are (25 x 24 x 23 x 22 x 21) / (5 x 4 x 3 x 2 x 1) = 53,130 sets.
The set of numbers that does not include the square root of 25 is the set of negative numbers, as the square root of 25 is 5, which is a positive number. Additionally, any set that only includes non-integer values, such as the set of rational numbers that are less than 5, would also not include the square root of 25. Thus, sets like the negative integers or irrational numbers less than 5 would also exclude it.
Their is 25 combinations
There are 480,700 combinations and I am not going to even try to list them!
There are 5245786 possible combinations and I am not stupid enough to try and list what they are!

5*4*3*2*1 = 120 combinations. * * * * * No. The previous answerer has confused permutations and combinations. There are only 25 = 32 combinations including the null combinations. There is 1 combination of all 5 numbers There are 5 combinations of 4 numbers out of 5 There are 10 combinations of 3 numbers out of 5 There are 10 combinations of 2 numbers out of 5 There are 5 combinations of 1 numbers out of 5 There is 1 combination of no 5 numbers 32 in all, or 31 if you want to disallow the null combination.
25
25 different combinations.
If you have to stick with positive whole numbers, then there are only two: 1 x 25 and 5 x 5
If the order of the five in the set makes a difference, there are (25 x 24 x 23 x 22 x 21) = 6,375,600 sets.If the order doesn't matter, then there are (25 x 24 x 23 x 22 x 21) / (5 x 4 x 3 x 2 x 1) = 53,130 sets.
