Question: Exercise 2.18 If X is a univariate random variable with distribution function F (x), then F(:L') is continuous at c if and only if P(X

Exercise 2.18 If X is a univariate random variable with distribution function F (x), then F(:L') is continuous at c if and only if P(X = c) = O. Prove by counterex- ample that this is not true if variables X and c are replaced by vectors X and c
