To give you a practical illustration we would be calculating the number of possible combinations in two different configurations of sets and subsets. Our combination calculator will allow you to calculate the number of combinations in a set of size n. Namely the 3 choose 2 and 4 choose 4.
Next enter r which is how large of a subset you would like to.
Usually alleles of the same gene noted as A1 A2 A3 A4 but I used ABCD for more visual effect and your convenience. Still because all are the same the result is 5 5 5 5 5 5 30 or 6 5 30. Consider an example problem where order does not matter and repetition is not allowed. This combination generator will quickly find and list all possible combinations of up to.
