+118687 I looked at one, although my answer may not be correct
The other already seemed to be looked at. I did not check for accuracy.
+865 Yeah, I checked at the one that geno3141 answered, and it seemed right and I understood the solution, but for some reason it's incorrect. I tried doing it again using his way and multiplied the fractions and got 64/405 but it was still incorrect.
So I'm not really sure about that problem.
