How many different possible combinations of the four different nitrogen bases taken three at a time?
Four of them.
How many combinations of four numbers are there in 16 numbers?
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.
How many 5 digit combinations are there for the numbers 1 through 59?
It's just a combination of 59 objects chosen five at a time which means (59*58*57*56*55)/(5*4*3*2*1)=5,006,386. Order does not matter in this calculation, which is why it is a combination not a permutation.
How many combinations can you make out of 26 letters?
There are 26! (which means 26*25*24 all the way to 1) permutations. this comes to 403,291,461,100,000,000,000,000,000 different combinations. If it takes you thirty seconds to write out one combination, then it would take 383,123,823,100,000,000,000 YEARS to write all the combinations. To put this into context, the universe (and possibly time itself) is only 13,700,000,000 years old.
What are the possible combinations of numbers 0 through 9 if any numbers cannot be repeated?
There are 10 combinations of 1 number,10*9/(2*1) = 45 combinations of 2 numbers,10*9*8/(3*2*1) = 120 combinations of 3 numbers,10*9*8*7/(4*3*2*1) = 210 combinations of 4 numbers,10*9*8*7*6/(5*4*3*2*1) = 252 combinations of 5 numbers,210 combinations of 6 numbers,120 combinations of 7 numbers,45 combinations of 8 numbers,10 combinations of 9 numbers, and1 combination of 10 numbers.All in all, 210 - 1 = 1023 combinations.

How many combinations can you make with 90 3?
Combinations from 90 objects, taken 3 at a time is 90C3 = 90*89*88/(3*2*1) = 117,480.
How many combinations can be made from 32 items taken 4 at a time and how do you do it?
Do a web search for "permutations and combinations" to find the how. I make it 35,960.
How many permutations and combinations are there of 8 objects taken 5 at a time?
For the permutation the equation is (8!)/(5!) assuming there is no replacement. Which is 8*7*6 = 336 For combinations the equation is (8!)/((5!)(8-5)!) = (8!)/((5!)(3)!) = (8*7*6)/(6) = 56
How many different possible combinations of the four different nitrogen bases taken three at a time?
Four of them.
How many combinations are there of 8 numbers?
There is just 1 combination of 8 numbers taken 8 at a time.
How many permutations and combinations are there of 4 objects taken 3 at a time?
Permutations = 4 x 3 x 2 = 24Combinations = (4 x 3 x 2) / (3 x 2 x 1) = 24/6 = 6
How mani combination is biteewn 12 out of 24?
The number of combinations of N things taken P at a time is (N! - P!) / (N - P)! The number of combinations of 24 things taken 12 at a time is 1,295,295,050,649,599.
How many numbers of arrangements will there be for 10 objects taken 3 at a time?
10*9*8 = 720
How many combinations of four can you make out of 6?
type in your calculator C(6,4) like the combination of 6 things taken 4 at a time
What is the number of ways to arrange 3 objects from a set of 8 different objects?
How many different ways can we arrange 9 objects taken 3 at a time?
How many different permutations are there of 4 objects taken 4 at a time?
The number of different permutations of 4 objects taken 4 at a time is calculated using the formula ( n! ), where ( n ) is the number of objects. For 4 objects, this is ( 4! = 4 \times 3 \times 2 \times 1 = 24 ). Therefore, there are 24 different permutations.
How do you write a combination and permutation formula?
The combination formula is usually written as nCr representing the number of combinations of r objects at a time taken from n. nCr = n!/[r!*(n-r)!] The permutation formula is usually written as nPr representing the number of permutations of r objects at a time taken from n. nPr = n!/r! Where n! [n factorial] is 1*2*3*....*(n-1)*n
