Question

The covariance of two random variables X and Y on a sample space S, denoted by is defined to be the expected value of the random variable That is, 41. What is the expected number of bins that remain empty when m balls are distributed into n bins uniformly at random?

Answer 1

Answer:

The covariance of two random variables X and Yon a sample space S, denoted by Cov(X,Y), is defined to be the expected value of the random variable (X - E(X))(Y - E(Y)).
