Math problem- permutations: combination lock? - find a combination calculator lock
A combination lock is opened when the correct choice of three numbers (1-40, is selected included). How many different combinations are possible barriers?
The answer is 64000, but when I plug into the computer as is 4P3 59,280. What am I doing wrong?
I have tried to do is possible even 40 x 39 x 38 (the first three questions), and then I have 59,280.
