Part A: There is a probability of 0.08 that a vaccine will cause a certain side effect. Suppose that a number of patients are inoculated with the vaccine. Find the probability that. a) more than 5 patients must be vaccinated in order to observe the first side effect. Part B: Newsweek in 1989 reported that 60% of young children have blood lead levels that could impair their neurological development. Assuming a random sample from the population of all schoo children at risk, how many students would you expect to have tested in order to find the first one to have these blood levels?
