17 of the 780 digital video recorders (DVRs) in an inventory are known to be defective. What is the probability that a randomly selected item is defective? Express your answer as a percentage rounded to the nearest hundredth.
Total DVRs = 780
Defective DVRs = 17
P(Defective DVRs ) = n(Defective DVRs) / Total DVRs
= 17 / 780
= 0.0218
= 2.18%
