Don't you want X1, X2, X3 to be ind? Otherwise V(L) would have some covariance terms? or is that implied by "random" sample?

I believe "random" sample implies independent (at least when dealing with a continuous distribution, or a discrete distribution with replacement).

I don't think it could be solved if the samples were dependent. There would not be enough given information to solve for the covariance.

How to explain actuarial exams to someone else...

Good Einstein quote - "One had to cram all this stuff into one's mind for the examinations, whether one liked it or not. This coercion had such a deterring effect on me that, after I had passed the final examination, I found the consideration of any scientific problems distasteful to me for an entire year."

A random sample is defined as a finite collection of independent identically distributed random variables. This concept is on exam P, and you do need to know it.
