Question

Approximately 10.3% of american high school students drop out of school before graduation. choose 10 students entering high school at random. find the probability that all 10 stay in school and graduate

Answer 1

Let n = 10, p = 0.897, x = 10 Computing for the probability that 10 students will graduate from high school, we use the formula P (X) = 10 ! / (0 ! 10 !) (0.897) 10 (0.103) 0 = 0.337
Therefore, 0.337 is the probability that 10 students will graduate from high school
