Question: It is estimated that 75% of the freshmen entering a particular (4 year) College degree will graduate from it in four years. Let X denote the number of freshmen graduating in four years from a random sample of 5 incoming freshmen students.

  1. What distribution does X follow? (b) Compute the probability that exactly three students will graduate in four years. In a particular year, 400 students enter the college. (c) Find the mean and standard deviation of the number of these students graduating in four years. (d)Use a normal approximation to compute the probability that at least 80% of these 400 students graduate in four years.
