Step 1
We can use the binomial distribution formula for this: P(X=k) = (n choose k) * p^k * (1-p)^(n-k) where X is the number of students who graduate in four years, n is the sample size (6), p is the probability of a student graduating in four years (0.25), and k is Show more…

According to the Chronicle of Higher Education, there is a 54% probability that a randomly selected incoming freshman will graduate from college within 6 years. Suppose that 10 incoming freshmen are randomly selected. a) What is the probability that exactly 6 of the 10 selected students will graduate from college within the next 6 years? b) What is the probability that exactly 4 of the 10 selected students will graduate from college within the next 6 years?

At a local community college, 40% of students who enter the college as freshmen go on to graduate. Seven freshmen are randomly selected. b. What is the probability that at most six will graduate from the local community college? (Do not round intermediate calculations. Round your final answer to 4 decimal places.)
