Answer) According to the question, six out of 50 digital video recorders are defective,
And we need to find the probability that a randomly selected digital video recorder is defective,
So the answer to this question is,
P(DVR is defective) = 6/50
or six divided by 50, which will give 0.12 as the answer.
So the required probability is 0.12.
