Solve the following problems:

1. How many numbers less than $500$ can you make using the digits $0, 2, 4, 6, 8$? Digits can be used over. A number cannot start with a zero.

   Hint (a):

   How many numbers are possible in the hundreds position?
   How many numbers are possible in the tens position?
   How many numbers are possible in the ones position?

   Step (a):

   Multiply the number of possibilities together.

2. How many numbers less than $500$ are there if the digits $0, 2, 4, 6, 8$ cannot be repeated? The lead digit cannot be zero.

   Hint (b):

   Refer to part (a) for help.

   Answer (b):

   $2 \cdot 4 \cdot 3 = 24$
