Find the probability that Jack-Jill is greater than 0. You subtract the means, you add the variance, and then use a Z-table.

Definitely. His score is NOT a random variable--it is inversely proportional to her hotness.

That sounds like a conditional RV to me.
Solve for the joint PDF! They're obviously not indepedent, so you're stuck trying to solve for the marginal then...
