A box contains four tickets labeled 1, 2, 3, 4. Draw two tickets(without replacement). Let U be the smaller number and let V be the larger number.

(a) Display a joint distribution table for (U,V), showing probabilities for all possible pairs (u,v). (Like Table 3 at the top of page 145)

(b) Give the distribution table (displaying values and their probabilities) for the distribution of V.

(c) Find E(V).

(d). Find E(U+V). (HINT: There's a slick way to see what this number is. If you don't see the slick trick right away, work out the answer and then think about it.)
