They are: XY, XZ, and YZ. Thus, there are 3 possible combinations. Another approach is to use Rule 1. Rule 1 tells us that the number of combinations is n! / r! (n - r)!. piloton m9 plus

"WebPermutation-based probabilities are calculated as the proportion of permutations in which the computed value of the test statistic is equal to or more extreme than the actual value. This calculation is easier to do mentally if the denominator is a multiple of ten, such as 1,000, though computationally there is no requirement to do this. " - Permutation in statistics
