*** SOLVE WITHOUT DERIVATIVE, USE GRAPHING CALCULATOR FUNCTION AND SHOW STEPS
4. Uniform Distributions. A random number generator randomly selects a number from -2 to 1.
It is equally likely to select any number from this interval [-2,1]. We can view this random
variable as a continuous random variable.
(a)
What is the constant height required to ensure that the area between the x axis and the
curve is exactly one in this case (note since this is a uniform distribution the density curve is
a horizontal line)?
(b)
What is the probability that a randomly generated number is less than -1?
(c)
What is the probability that a randomly generated number is greater than -1?
(d)
What is the probability that a randomly generated number is greater than 0.5?
(e)
What is the probability that a randomly generated number is either greater than 0.5 or less
than -1?
