For incoming freshman, Texas A&M reports an overall 4 year graduation rate of 75%. For a random sample of 8 entering freshman, use the Binomial Distribution to answer the following:
A. What is the probability that 5 will graduate in 4 years?
B. What is the probability that 4 or more will graduate in 4 years?
C. What is the expected number E(x) to graduate in 4 years from this sample?
Homework Answers
Here we have over all 4 year graduation rate of 75%
Means p= 75%=0.75
And random sample of 8 freshman is taken
So n=8
This is Binomial Dustribution with n=8 and p=0.75

4. Over the last 10 years, a company's annual earnings increased year over year seven times and decreased year over year three times. You decide to model the number of earnings increases for the next decade as a binomial random variable. A. What is your estimate of the probability of success, defined as an increase in annual earnings? For Parts B, C, and D of this problem, assume the estimated probability is the actual probability for the next decade. B....
