Will the production process permit an acceptable fit of all three parts combined with a specification of $5+0\mathrm{.}081$ inches at least $99\mathrm{.}73\%$ of the time? Note that $5$ is the sum of the specifications of Parts $1,2,$ and $3$ while $0\mathrm{.}081$ is the sum of the tolerances for Part $1,$ Part $2,$ and Part $3.$
