Approximately 10.3% Of American High School Students Drop Out Before Graduation. Choose 10 Students Entering High School At Random. Find the probability that at least 6 will graduate

Find P(6), P(7), P(8), P(9), and P(10).
The easiest way to do this would be to use a binomial probability function table.
Find each value, then add together for your probability. 
Approimately 10.3% of American high school students drop out of school before gradution. Choose 10 students entering high school at random. Find the probability that (Assume binomial distribution): a. Exactly two drop out b. At least 7 graduate c. All ten stay in school and graduate

Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Round your answer to four decimal places.)
