The number of birth defects in a region is commonly modeled as having a binomial distribution, with a rate of three birth defects per 100 births considered a typical rate in the United States. a. What is the probability a county that had 50 independent births during the year would have more than twice as many birth defects as expected? b. What is the probability a county that had 150 births during the year would have more than twice as many birth defects as expected?
