  We enumerate the number of monotonic lattice paths starting at $(0,0)$ and
terminating at $(m,n)$ in which $l$ of the first $k$ steps lie below the line
$y=x\ (0\leq k\leq m\leq n)$. These closed formulas consist of terms which are
a product Catalan numbers, ballot numbers and binomial coefficients. We then
apply the combinatorial formulas to failure analysis by deriving a probability
distribution that compares the performance of a $k$-out-of-$m$ system to a
$k$-out-of-$n$ system of continuous, independent, and identically distributed
random variables. Lastly, we provide asymptotics in a few special cases of
$k,m,n$ and leave others as conjecture.
