Question

Determine the written description of the complement of the given event. When seven job applicants are tested for a certain ability​, at least one of them tests positive. Choose the correct answer below. A. All of them test positive B. None of them test negative C. All of them test negative D. More than one of them test negative

Answer 1

Answer:

The written description of the complement of the given event is More than one of them test negative

Explanation:

The sentence states that seven people were tested and it also says that at least one tests positive, this means that the minimum number of positive results is one, which makes options A, B, and C incorrect in terms of probabilities and statistics, option A and C says that ALL of them are positive or negative respectively which can nos be supported by the expression "at least", then option B is a restatement of option A. Option D is the one that paraphrases the sentences correctly by saying that at least it was one even there could be more, but it does not assure that all.
