It's impossible for 2 factors of 12 to add up to 16. So there would be no answer to that.
The probability of rolling an even number on the first dice is 1/2(3/6)
The probability of rolling an even number on the first dice is also 1/2 (3/6)
So the probability of getting two even numbers on both dice is 1/2*1/2=1/4
39/6= 6.5 then u multiply
6.5 times 4 = 26
which 26 is your answer
30 times 86 equals 2580 and 4 times 86 equals 344 add those together and you get 2924
