No i cant frickin remember it for the life of me!! >.<
it is n!/(n-k)!
plug and solve
It's just like the Combination formula without any division. multiply descending values until you've written out how many numbers the digit after the P is:
7P3 = 7*6*5 (see, three numbers, descending from 7)
yeah, guys, actually the answer is not D it is A
the equation should be read as we have the number of permutations of 7 taken 3 at a time.
so P(7,3)= "seven factorial divided by three factorial"
D is correct
bah, what would wolframalpha know :P
oh i get it... did it without the difference :? guess i'll have to learn something today.
