Hi, please I need help with these questions. I would appreciate it if you help me, thank you

Five friends took the final exam and the probability that each of them would get an \"A" is 1/2. Use Binomial distribution (Lecture 27) to answer the following questions. We are interested in total number of A's among these five friends. 17. What are the n and p in this (binomial) model? Q) a. n=5 p=1/2 O b. n=A and p=1/5 O c. n=5 p=1/5 and k=0,1,2,3,4,.. 0 d. None of the above. 18. What is the probability that 2 out of 5 friends got A's on the exam? Oa. G)=1o O b. 0.046875 Q) C. 0.3125 0 d. None of the above. 19. Which of these is the most likely to happen? 0 a. None of the friends got an A. O b. All of them got A's. O c. Only one friend got an A. Q) d. Only two friends got A's
