So you take the amount of times rolled times the number of sides. Take all possible numbers it could be and put it over the total. Which would be 2/12. You simplify by dividing by 2 to get 1/6
i just did it and got 1/12 if the second number is even there are only gonna be 3 even numbers and if the second one is even you do 36/3 then you get 12 so it will be 1/12
