Question

Assume you are rolling two dice ; the first one is red and the second one is green . Use a systematic listing to determine the number of ways you can roll a total of 5 on the two dice

Answer 1

If we roll two dice, how many different pairs of numbers can appear on the upturned faces?
SOLUTION: To emphasize that the dice are different, we assume one is red and the other
green. Clearly, a red 2 and a green 3 is not the same as a red 3 and a green 2. We will use
ordered pairs of the form (red number, green number) to represent the pairs showing on
the dice. For example, (4, 5) represents a red 4 and a green 5. Figure 13.3 on page 626
illustrates this situation.
The leftmost set of six branches in Figure 13.3 shows pairs corresponding to 1 on the
red die and either a 1, 2, 3, 4, 5, or 6 on the green. These branches correspond to the pairs
(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), and (1, 6). Similarly, the second set of six branches

Answer 2

that should help. just dont look at the textbook part
