Use the counting principle to determine the number of points in the sample space. (My answer:6)
Construct a tree diagram to represent this situation. (My Answer: 369T, 369R,639T,639R,963T,963R)
List a sample space. ?
Determine the exact probability of creating a mini license plate with a T. (My answer:3/6=1/2) Give solution in reduced fraction form.

There are 3 ways to pick the first number, then, since you aren't allowed duplicates, there are only 2 ways to pick the second number, and then 1 way to pick the third number. 3 times 2 times 1 is 6, so there are 6 ways to pick the numbers for each of the 2 letters. Total of 12.
