Step 1
0. We can do this by using the binomial distribution formula: P(X = k) = (n choose k) * p^k * (1-p)^(n-k) where: - n is the sample size (in this case, 5) - k is the number of successes (in this case, 0) - p is the probability of success (in this case, 0.2) So, Show more…

Assume that the GPA of a randomly chosen college student has a normal distribution with mean 2.84 and standard deviation 0.42. a. Find the probability that a randomly chosen college student has a GPA of at least 2.30. b. If ten college students are independently selected, what is the probability that exactly nine of them have a GPA of at least 2.30.
