A six sided die is rolled three times. List possible outcomes and find the probability of rolling exactly one 6.

1. Are you sure that they want you to "list" all the outcomes?
There are 216 of them. (6x6x6=216)

If you have to list them, do it systematically, e.g.
1 1 6
1 1 5
...
1 1 1
1 2 6
1 2 5
....
1 2 1
1 3 6
.....
....
1 6 1
...
2 1 6
2 1 5
etc

To have only one 6, it must look like this
6 x y, x 6 y, x y 6, where the x and y are NOT 6
number of those = 3x5x5 = 75

prob (exactly one 6) = 75/216 = 25/72
