## twenty-four to nil

**A**nother puzzling question on X validated, where the expectation of a random sum of deterministic vectors is to be computed. (That is, the sum involves a random number of terms.) Without enough detail to understand why this proves a difficulty, given that each deterministic vector is to be invoked at most once. Nonetheless, my (straightforward) answer there

proved much more popular (in terms of votes) that many of my much more involved answers there. Possibly because both question and answer are straightforward.
