Question description

An extended warranty is a prolonged warranty offered to consumers by
the warranty administrator, the retailer, or the manufacturer.  A recent
report in The New York Times (November 23, 2009) suggests that
20.4% of laptops fail over three years.  Roberto D’Angelo is interested
in an extended warranty for his laptop.  A good extended warranty is
being offered at Compuvest.com for \$74.  It will cover any repair job
that his laptop may need in the next three years.  Based on his
research, he determines that the likelihood of a repair job in the next
three years is 13% for a minor repair, 8% for a major repair, and 3% for
a catastrophic repair.  The extended warranty will him \$80 for a minor
repair, \$320 for a major repair, and \$500 for a catastrophic repair.
These results are summarized in the following probability distribution.
