Unformatted text preview: ( X < 7) ,P ( X ≤ 13) and P ( X ≥ 3). 2. Let X be a continuous random variable with probability density function f X given by f X ( x ) = ± 2 e2 x x > x ≤ 1. Is f X a probability density function? Why? 2. Calculate P ( X ≤ 2) and P ( X < 2). 3. Calculate P ( X > 2), and P ( X > 3). 4. Calculate P ( X > 5  X > 2). What do you learn from it? 1...
