  Precedence order is a natural type of comparison for random variables in
numerous engineering applications (e.g., for the stress-strength modeling). In
this note, we show that, for a $k$-out-of-$n$ system, redundancy at the
component level is superior to that at the system level with respect to the
stochastic precedence order. Cases of active and cold redundancy are
considered. Similar results for other stochastic orders were intensively
discussed in the literature.
