Suppose that the probability of a student successfully completing Mth102 with a C or better is 75%, and 5 students are randomly selected from the population of Mth102 students at ECC. If we define X as the number of Mth102 students who successfully complete the course with a C or better, does X follow a binomial distribution? Check all statements below that apply
Two distinct outcomes - yes, each student either earns a C or better or does not
Fixed number of trials - no, we do not know how many students will be successful. Fixed number of trials - yes, there are 5 students
Constant probability - yes, the probability for each student (since they are randomly selected) is 0.75
Two distinct outcomes - no, because students can earn an A, B, C, D, or F.
Trials are independent - yes, they are randomly selected
Constant probability - no, the probability is not the same for each.
Trials are independent - no, because the students could be related.
