3. Suppose a value is chosen “at random" in the interval [0,6]. In other words, x is an observed value of a random variable X 4 U (0, 6). The random variable X divides the interval [0,6] into two subintervals, the lengths of which are X and 6 – X respectively. Denote by Y the length of the shorter of the two intervals. (a) Draw a picture which illustrates the value of Y as a function of the possible values of X. (b) Describe the support of Y and find the probability P(Y > y) for any given y. (c) Find both the cdf and the pdf of Y. Can you tell the name of the distribution of Y?

3. Suppose a value is chosen “at random" in the interval [0,6]. In other words, x is an
observed value of a random variable X 4 U (0, 6). The random variable X divides the
interval [0,6] into two subintervals, the lengths of which are X and 6 – X respectively.
Denote by Y the length of the shorter of the two intervals.

of X.
(b) Describe the support of Y and find the probability P(Y > y) for any given y.

Y?
