I think I figured out the second answer.... 1/12 ??
(1/2)17+(1/6)=
Since a coin has 2 sides, the probability of landing a heads is 1/2, and because there are 17 of them, you multiply the 1/2 by 17. The die is being rolled once so the porbability of rolling a 4 is 1/6. Add them together you get what you need.
