Cоnsider the setup оf yоur Midterm 1. We will model your score on Midterm 1 аs а rаndom variable which is the total number of questions you got correct, multiplied by a constant, which is the number of points per question in Midterm 1. We will model the number of questions you got correct as a discrete uniform random variable over {0,1,...,N}, and N is the total number of questions. What is the probability that your total score is divisible by 5? (Don't forget that 0 is a possible score under this model).

We will model the number of questions you got correct as a sum of N iid Bernoulli random variables each with parameter p=[p] and N is the total number of questions. What is the probability that your score is divisible by 7?  (Don't forget that 0 is a possible score under this model).
