The probability is 1% that an electrical connector that is kept dry fails during the warranty period of a portable computer. If the connector is ever wet, the probability of a failure during the warranty period is 5%. If 90% of the connectors are kept dry and 10% are wet, what proportion of connectors fail during the warranty period? Let: D = electrical connector is dry D' = electrical connector is not kept dry (i.e., is wet) F = connector fails during warranty period F' = connector does not fail during warranty period Match the correct probability description to each given probability value
