6 5/6 is your answer
6 can go into 41, 6 times giving you 36. Then you subtract 41 and 36 which will give you the remaining number which is 5. You then take the 5 and out it over 6.
Use the distributive property.
4(4a + 5) = 4 * 4a + 4 * 5 = 16a + 20
Answer: 16a + 20
I believe it is 2/12, because they each have a 1/6 probability of rolling a 6.
