You roll a fair 3-sided die (labelled 1, 2, and 3; pictured below) 3 times. Two possible outcomes are 122 and 321, rolling a 1 followed by two 2s and rolling a 3 followed by a 2 then a 1. Express the sample space in exactly the following format: {122, 321}(note the curly braces, comma, and space). You'll need to add many more triplets. Sort them in ascending order by the first roll, then the second, then the third. So, 122 comes before 321 because 1 is before 3. Similarly, 121 would be before 122 since the first numbers are both 1s, the second numbers are both 2s, and the third numbers are, in order, 1 then 2.
