Mole to mole conversion !?

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.
