a) The probability of each outcome must be greater than or equal to 0, so this is a required condition. b) The sum of the probabilities of all possible outcomes must be equal to 1, so this is also a required condition. c) The expected value of the random Show more…

Suppose that a random variable X has the probability density function f(x) = 2x for any x ∈ (0,1), and 0 otherwise. Let F(x) be its cumulative distribution function. Which of the following statement is true? (Circle one only.) A X is a discrete random variable D None of the above.

Which of the following is not true about a probability density function for a random variable X? A. The total area under the density function above the x-axis is 1.0 B The area under the density function between a and b is F (a) - F (b) C. The area under the density function between a and b is F (b) - F (a) D. For any value of a, P(X < a) = P(X <= a)
