An aerosolized vaccine for measles was developed in Mexico and has been used on more than 4 million children since
1980. Aerosolized vaccines have the advantages of being able to be
administered by people without clinical training and do not cause injection-
associated infections. The percentage of children developing an immune
response to measles after receiving the subcutaneous injection of the vaccine is 95%,,itis85%. Thereare20 children to be vaccinated for measles using the aerosolized vaccine in a small rural village in India. We are going to count the number who developed an immune response to measles after vaccination. (b) What is the probability that at least one child does not develop an immune response to measles after receiving the aerosolized vaccine? What would be the probability that at least one child does not develop an immune response to measles if all children were vaccinated using the subcutaneous injection of the vaccine?
