2. A company produces antidote injection vials. Suppose the probability to have a defective vial is 1 per 5000 vials:
(a) If 5 vials are randomly selected,
i. what is the average number of vials you expect to be defective?
ii. what is the probability that at least one of them is defective?
(b) If 10,000 vials are randomly selected, (think of this as an 'area of opportunity')
i. what is the average number of vials you expect to be defective?
ii. what is the probability that at least one of them is defective?
