Assuming that the question is about
there are 2,627,625 combinations.
The number is only 24 times as large is the order of the groups does, in fact matter. However, if the 4 groups can be of any size (provided their total is 16), the question goes beyond my ability - particularly at this time of the day!
There are many combinations of two numbers that add up to 36. One combination is 20 + 16
There are 18C4 = 18!/[18-4)!4!] = 18*17*16*15/(4*3*2*1) = 3060 combinations.
If they can repeat, then: 17^6=24,137,569 If they can't repeat, then: 17*16*15*14*13*12=8,910,720
2 to the power 16.
The number of possible combinations is 2^4=16. Depending on what you're representing, this could be positive integers (0 to 16), positive and negative (-8 to 7), or some kind of floating point... Depends on what you mean (But whatever kind of numbers you mean, there are still 16 of them.)
16
16 x 15 / 2 ie 120
To calculate the number of 4-number combinations possible with 16 numbers, you would use the formula for combinations, which is nCr = n! / r!(n-r)!. In this case, n = 16 (the total number of numbers) and r = 4 (the number of numbers in each combination). Plugging these values into the formula, you would calculate 16C4 = 16! / 4!(16-4)! = 1820. Therefore, there are 1820 possible 4-number combinations with 16 numbers.
There are many combinations of two numbers that add up to 36. One combination is 20 + 16
they can be 2 groups of 16, 4 groups of 8, 8 groups of 4, or 16 groups of 2
If order matters and a number cannot be repeated, then there are 16x15x14x13 = 43680 different combinations. If order does not matter then you must divide by the number of ways you can rearrage the same 4 numbers i.e. divide by 4x3x2x1=24 so you can select 4 numbers from a group of 16 in 43680/24 = 1820 ways. In mathematical terms there are 43680 permutations of 16 numbers taken 4 at a time and 1820 combinations of 16 number taken 4 at a time.
Assuming that "number" means digits and that it is permutations (rather than combinations) that are required, the answer is 816 which is 281.475 trillion (approx).
There are 18C4 = 18!/[18-4)!4!] = 18*17*16*15/(4*3*2*1) = 3060 combinations.
There are five ways to do this, if you include 32 'groups' with one member each.The others are 2 groups of 16, 4 groups of 8, 8 groups of 4 and 16 groups of 2.
If you allow for zeros, that's 10^16, which is ten quintillion, or 10,000,000,000,000,000. If not, it's 9^16, which is 1,853,020,188,851,841, or 1.85 quintillion. (1.85x10^15)
If they can repeat, then: 17^6=24,137,569 If they can't repeat, then: 17*16*15*14*13*12=8,910,720
