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)

2. Let X be a continuous random variable. Let R be the set of all real numbers, let Z be the set of all integers, and let Q be the set of all rational numbers. Please calculate (1) P(X ? R), (2) P(X ? Z), and (3) P(X EQ)
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...
