Thanks Jazz519. I agree, x^2, not x^3. Not sure what I did there, maybe I looked at the 3 coefficient for too long! Lol.

My answer to 12ei was 2/5. On the right, next to the question. I wrote 3/5 next to Odd on my tree diagram (which I didn't end up really looking at).

Thanks for checking it over and replying! There's always at least 1 careless mistake!
