Whooping cough (pertussis) is a highly contagious bacterial infection that was a major cause of childhood deaths before the development of vaccines. About 80 % of unvaccinated children who are exposed to whooping cough will develop the infection, as opposed to only about 5% of vaccinated children. A group of 20 children at a nursery school is exposed to whooping cough by playing with an infected child.

(b) What is the probability that no more than 2 of the 20 children develop infections if all 20 have been vaccinated?
