State license plates contain
different numbers and letters to
create a unique identification number
for each car. Make your own license
plates each containing a 4-digit
number. Using the digits 1, 3, 7, and 9
without repetition, how many 4-digit
numbers can you form?
You can use a tree diagram to create
the following list of license plates. Are
you sure you found them all?
Hint: Find 4!
You can make 24 unique license
plates using 1, 3, 7 and 9 without
repetition.
