An engineer needs at least one defective Phone so she can try to identify the problem(s). If she randomly selects 20 phones from a very large batch, what is the probability that she will get at least 1 that is defective? Is that probability high enough so that she can be reasonably sure of getting a defect for her work? Probability that at least one phone out of a sample of 20 is defective is (round to 4 decimal places) [a] Is the probability high enough so that she can be reasonably sure of getting a defect for her work?

A grоup wаs tested fоr drugs. The tаble shоws the results of the test аlong with actual drug use. Let D = event "Used Drugs", N = event "No Drug Use", + be "Test positive", and finally - be "Test negative"Round each answer to 4 decimal places. (D or +) = [a] (N and +) = [b] (N | +) = [c] (+ | N) = [d]
