Let x be a continuous random variable then any real number of x is P(X<x) ≤ P(X ≤ x)
(random variable X is called continuous if its values x form a “continuum”, with P(X = x) = 0 for each x)

Answer if each X defined as below is a random variable or not. If X is not a random variable, try to create a random variable X' based on the outcome of X. (a) X is defined as the genders of next two consecutive births in a particular hospital. (b) X is defined as the outcome of a coin toss experiment in which a coin is tossed three times. (c) X is defined as 0 when a randomly chosen adult...
