How many possibilities are there if you are creating a 4-digit password using the digits 0 through 9? You may repeat numbers.

A.) 40
B.) 6,561
C.) 5,040
D.) 10,000

Respuesta :

Each number had 10 possibilities. So to calculate the number of possibilities for two numbers multiply 10 by 10. This means that for all 4 digits the number of possible permutations is 10x10x10x10 or 10 to the power 4. This equals to 10,000 therefore D.
