Category: Statistics

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 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 save 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.

Type of Repair Probability Repair Cost

None 0.76 $0

Minor 0.13 $80

Major 0.08 $320

Catastrophic 0.03 $500
