Hepatitis C is spread primarily through contact with the blood of an infected person and is nearly always transmitted through needle sharing among intravenous (IV) drug users. Suppose that in a month's time, an IV drug user has a 30% chance of contracting hepatitis C through needle sharing. What is the probability that 3 out of 5 IV drug users become infected with hepatitis C in a month's time? Assume that the drug users live in different parts of the country.
