A random variable X has a distribution p(X=k) = A / (k(k+1)), k = 1,2,...,4, where A is an constant. Then compute the value of p(1<=X<=3)
The answer will be either: 2/3, 3/4, 5/6, or 15/16
A discrete random variable X is uniformly distributed among −1,0,...,12. Then, what is its PMF for k=−1,0,...,12
The answer will be either: p(X = k) = 1/12, 1/13, 1/14, or 1
