The student body of a large university consists of 65% female students. a random sample of 8 students is selected. what is the probability that among the students in the sample at least 7 are female? a. 0.1064 b. 0.0896 c. 0.1373 d. 0.1692

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
