Question 738327: If there are 10 cars, and 10 parking spots, how many different ways can the cars be arranged?
Answer by fcabanski(1391)   (Show Source):
You can put this solution on YOUR website! This is a Permutation because order matters. Car 1 in Spot 1 is different from Car 1 in Spot 2: 1,2,3,4,5,6,7,8,9,10 is different from 1,3,2,4,5,6,7,8,9,10...
This is 10 P 10 = 10!/(10-10)! = 10!/1 = 10*9*8*7*6*5*4*3*2*1 = 3,628,800
Hope the solution helped. Sometimes you need more than a solution. Contact fcabanski@hotmail.com for online, private tutoring, or personalized problem solving (quick for groups of problems.)
