Question 36288: Can somone answer this problem?
The number of permutations of two items from a data set is always two times the number of combinations when taking two objects at a time from the same data set
Explain why this statement is true or false Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! nC2 = n!/[(n-2)!2!]
nP2 = n!/[(n-2)!]
The combination is 1/2 the permutation, so
the permutation must be two-times the combination.
