7.A bakery uses 2000 raisins to make 100 loaves of bread. Let X be the number of raisins of each loaf. X follows a binomial distribution with n=2000, p 1/100. Using the central limit theorem.(normal approximation} a) find the probabilities: P(20 28) 1:d .. b) find the probability that average number of raisins in 25 randomly chosen loaves exceeds 28. c) Why is it possible to apply central limit theorem to this problem?
