Does the number of permutations always exceed the number of combinations?
No. The number of permutations or combinations of 0 objects out of n is always 1. The number of permutations or combinations of 1 object out of n is always n. Otherwise, yes.
How many 4 number combinations are there using 1 2 3 4 5?
There are 120 permutations and 5 combinations.
How many5 number combinations are there in the numbers1to43?
On a calculator: 43C5 = 962598 This is for combinations and not permutations, so in essence, the order of the 5 number combinations does not matter. Yours Truly, Mr Greatness
How many different combinations are possible is a coin is tossed once and a number cube is tossed twice?
The number of combinations - not to be confused with the number of permutations - is 2*21 = 42.
How can you find the number of permutations of a set of objects?
If there are n different objects, the number of permutations is factorial n which is also written as n! and is equal to 1*2*3*...*(n-1)*n.
Does the number of permutations always exceed the number of combinations?
No. The number of permutations or combinations of 0 objects out of n is always 1. The number of permutations or combinations of 1 object out of n is always n. Otherwise, yes.
How do you find permutation?
If there are n objects and you have to choose r objects then the number of permutations is (n!)/((n-r)!). For circular permutations if you have n objects then the number of circular permutations is (n-1)!
The number of permutations of n objects taken all together is?
The number of permutations of n objects taken all together is n!.

How many 3 number combinations are possible with 1234?
Just 4: 123, 124, 134 and 234. The order of the numbers does not matter with combinations. If it does, then they are permutations, not combinations.
The number of permutations of 5 things taken 2 at a time is 20?
Not quite. Number of combinations is 20, number of permutations is 10. Any 2 from 5 is 10 but in any order doubles this.
What is the number of distinguishable permutations?
The formula for finding the number of distinguishable permutations is: N! -------------------- (n1!)(n2!)...(nk!) where N is the amount of objects, k of which are unique.
How many combinations are there if there are 8 numbers and you have a 16 number combination?
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).
