If you take any one of the three digits of 3, 2 and 1, what is the possibility of getting an even number______ ．

Using 1, 2 and 3 to form a three digit combination is 1231322133231312321. There are only two even numbers, so the possibility that the three digits are even numbers is: 1 △ 3 = 13. Answer: the possibility is 13, so the answer is: 13
