Math Problem Statement

Assume two six-sided dice are rolled each with the numbers 1, 2, 3, 4, 5, and 6. The first one is red, and the second one is green. Use a systematic listing to determine the number of ways to roll a total of 5 on the two dice.

Solution

The problem asks to determine the number of ways to roll a total of 5 using two six-sided dice. Let's break this down systematically.

Step-by-step solution:

Each die has six sides with numbers: 1, 2, 3, 4, 5, and 6. We will systematically list all combinations where the sum of the two dice equals 5.

Dice Combinations:

  • If the red die shows 1, the green die must show 4. → Combination: (1, 4)
  • If the red die shows 2, the green die must show 3. → Combination: (2, 3)
  • If the red die shows 3, the green die must show 2. → Combination: (3, 2)
  • If the red die shows 4, the green die must show 1. → Combination: (4, 1)

Total:

There are 4 ways to roll a total of 5 on two dice.
