first find the number of possible lists
= C(12,10) = 66
but each of those can now be arranged, or ordered, in 10! ways
so the number of ordered lists = 66(10!)
= 239500800
= C(12,10) = 66
but each of those can now be arranged, or ordered, in 10! ways
so the number of ordered lists = 66(10!)
= 239500800
