Approximating Binomial Probabilities In Exercises 2328, determine whether you can use a normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use a binomial distribution to find the indicated probabilities Foreign Language A survey of U.S. adults found that 51% think that highschool students should be required to learn a foreign language.
