In the process of producing engine valves, the valves are subjected to a first grind. Valves
whose thicknesses are within the specification
are ready for installation. Those valves whose
thicknesses are above the specification are
reground, while those whose thicknesses are
below the specification are scrapped. Assume
that after the first grind, 74% of the valves meet
the specification, 15% are reground, and 11% are
scrapped. Furthermore, assume that of those
valves that are reground, 90% meet the
specification, and 10% are scrapped.
Find the probability that a valve is ground only once. Round
the answer to two decimal places.
