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?
(f)
What is the probability that a randomly generated number is 0.5?

4.60 The sum of two uniform random numbers. Generate two random numbers between 0 and 1 and take Y to be their sum. Then Y is a continuous random variable that can take any value between 0 and 2. The density curve of Y is the triangle shown in Figure 4.12. (a) Verify by geometry that the area under this curve is 1. (b) What is the probability that Y is less than 1?

Suppose 6 numbers are generated by a computer, each uniform on the interval (0, 1). Let Y be the random variable representing the smallest of the numbers. (a) Show that the probability density of Y is given by py (t) -61-t)5, 0t <1 [51 Hint: The probability density for the r-th largest random variable can be derived using the Beta distribution by letting a = r and ?-n-r +1. (b) What is the probability that the smallest number is less...
