How many combinations are there with 5 things?
How many combinations are there with 5 things?
Note that your choice of 5 objects can take any order whatsoever, because your choice each time can be any of the remaining objects. So we say that there are 5 factorial = 5! = 5x4x3x2x1 = 120 ways to arrange five objects. In general we say that there are n!
How many combinations are there with 8 items?
Note: 8 items have a total of 40,320 different combinations.
How many ways can you arrange 10 things?
The answer depends on the frequency of each letter. If the letters are all different, then they can be arranged in 10! = 10*9*8*7*6*5*4*3*2*1 = 3,628,800 ways. If some of the letters are repeated, the number of arrangements will be 10!
How many ways can you arrange 6 things?
720 arrangements
So the six letters can be a combination of 6×5×4×3×2×1 letters or 720 arrangements.
How do you list all possible combinations?

How many combinations of 3 items are there?
3*3*3=27 unique possibilities. This number is small enough to enumerate the possibilities to help your understanding (like the other tutors did), but the digits^base expression (with “^” meaning exponentiation) is important.
How many combinations are in a 10 digit code?
If repetition is allowed, then the number of permutations of 10 digits is 10,000,000,000. If repetition is not allowed, then the number of permutations of 10 digits is 3,628,800.
How do you calculate total number of combinations?
Combination Calculator. In finite mathematics a combination is most typically calculated using the formula C(n,r) = n!/r!(n-r)!. In this formula n represents the total number of items and r represents the number of items to choose. The formula is modified depending on the importance of item order and repeating items in the set of allowed results.
How to calculate all possible combinations?
you can use the same item more than once.
What is the formula for the number of possible combinations?
The formula for combinations is generally n! / (r! (n — r)!), where n is the total number of possibilities to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52.
How do you find the number of combinations?
You can also calculate combinations in Excel using the function COMBIN. The exact formula is: =COMBIN(universe, sets). The number of four-character combinations that can be made from the alphabet is: =COMBIN(26, 4) or 14,950.
