(a) Complete the set to form the sample space of 36 elements. Note that each element is an ordered pair in which the entries are the numbers of points on the first and second rolls, respectively.
5 = {(1, 1), (1, 2),………, (2, 1), (2, 2),…}
(b) Complete the table and sketch the graph of the probability distribution, in which the random variable x is the sum of the two rolls.
x | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
P(x) |
(c) Use the table in part (b) to find
