Question 2: Binominal distribution ( It has been reported that in a certain university 2% of the 2 million international students receive special accommodations due to their disabilities. We studied a random sample of 25 students. Answer the following questions: a) b) Find the probability that exactly one received a special accommodation? Find is the probability that at least one received a special accommodation? Find the probability that the number among the 25 who received a special accommodation is within 2 standard deviations of the number you would expect to be accommodated? c)
