The antibiotic works great but research has found that 10% of patients experience sleeping disorders after taking the drug. You decide to test the drug with sample of 18 patients before you launch the new drug.

b) Find the probability that at least two patients experience sleeping disorders after taking the drug.

c) What proportion of patients do you expect to experience sleeping disorders in your sample? With what standard deviation?
