The probability of flu symptoms for a person not receiving any treatment is 0.02. In a clinical trial of a common drug used to lower cholesterol, 20 to 900 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu symptoms, estimate the probability that at least 20 people experience flu symptoms.
Hint: Apply normal approximation to the Binomial distribution or use The Sampling Distribution of a sample proportion to estimate the probability.
I have no clue how to get started or even how to go about starting it..
