2 is the smallest and 12 is the largest numbers you can have if 1+1 or 6+6 is received. 6:12
thats all I got for that.
1.
Here's a table of possible sum outcomes
1 1 1 6 6 6
1 2 2 2 7 7 7
1 2 2 2 7 7 7
1 2 2 2 7 7 7
6 7 7 7 12 12 12
6 7 7 7 12 12 12
6 7 7 7 12 12 12
Expected value =
2(9/36) + 7(18/36) + 12(9/36) =
2(1/4) + 7(1/2) + 12(1/4) =
1/2 + 7/2 + 3 =
8/2 + 3 =
4 + 3 =
7
The most likely outcome is 7 and its probability = 18/36 = 1/2
