A certain state has the highest high school graduation rate of all states at 90%. a. In a random sample of 20 high school students from the state, what is the probability that 18 will graduate? b. In a random sample of 20 high school students from the state, what is the probability than 17 or fewer will graduate? c. What is the probability that at least 18 high school students in our sample of 20 will graduate? a. What is the probability that 18 out of 20 high school students will graduate? The probability that 18 students will graduate is 0.285. (Type an integer or decimal. Round to three decimal places as needed.) b. What is the probability that 17 or fewer out of 20 high school students will graduate? The probability that 17 or fewer students will graduate is (Type an integer or decimal. Round to three decimal places as needed.)
