In one state, approximately 34.6% of residents had an asthma
attack in the last five years. Assume that having an attack is
independent from person to person. Assume that the households have
four residents per household. Estimate the probability that in 50
households, there are at least 45 households in which at least one
resident had an asthma attack in the last five years. (Hint: first
find the probability that in one household, there is at least one
person that had an asthma attack.)
