Under favorable weather conditions, the management of Flesher Farms expects its
raspberry crop to have a $120,000 market value. An unprotected crop subject to frost has
an expected market value of $80,000. If Flesher protects the raspberries against frost, the
market value of the crop is still expected to be $120,000 under frost-free conditions and
$180,000 if a frost occurs. What must be the probability of a frost for Flesher to be
indifferent to spending $20,000 for tents to provide frost protection?
