I asked my math professor and she said this is ok. I probably overthought the problem. Thank you very much!

I am expecting that from the fact that X(-1)(G) = {w in S such that X(w) is in G for all G in B(R) } is in F you can somehow show that |X|(-1)(G') = {w in S such that |X|(w) is in G' for all G' in B(R)} is also if F

Just mapping from (S,F) to (R, B(R))

Howdy guys. Given that X is a random variable how would you prove |X| to be one too? Thanks for any suggestions!
