Suppose that 3% of the 2 million high school students who take the SAT each year receive special accommodations because of documented disabilities. Consider a random sample of 20 students who have recently taken the test. (Round your probabilities to three decimal places.)(a) What is the probability that exactly 1 received a special accommodation?(b) What is the probability that at least 1 received a special accommodation?(c) What is the probability that at least 2 received a special accommodation?(d) What is the probability that the number among the 20 who received a special accommodation is within 2 standard deviations of the number you would expect to be accommodated? Hint: First, calculate ? and ?. Then calculate the probabilities for all integers between ? - 2? and ? + 2?.
