Two students are taking a 10 question test. Each question has 4 different answers. How many ways can each student answer the test? What is the probability that these two students get the same answers?
I know that to get the number of ways to answer, the number of students is irrelevant.
nk in this case is 410
I'm stuck on the second part of the question though. Any guidance would be helpful.
