Question
Suppose that 0.1% (= 0.001) of prescriptions written in Milwaukee contain an error. Find the probability of at least 2 prescriptions with an error (a)
Suppose that 0.1% (= 0.001) of prescriptions written in Milwaukee contain an error. Find the probability of at least 2 prescriptions with an error
(a) in a sample of 6 prescriptions;
(b) in a sample of 6000 prescriptions.
Note. In part (a), the exact probability is small; give it to 8 decimal places. In part (b), you should use the Poisson approximation.
Please solve clearly and correctly.
