C) 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? (

There is 0.014 proportion of connectors fail during the warranty period.

Step-by-step explanation:

Let A be the event that connector fails.

Let B be the event that connector wet.

P(B) = 10%

P(B') = 90%

P(A|B) = 0.05

P(A|B') = 0.01

So, we need to find the proportion of connectors fail during the warranty period is given by

Hence, there is 0.014 proportion of connectors fail during the warranty period.
