Q:

Hannah and Corrine are playing a game by rolling two cubes, each numbered 1 through 6. If the sum of the numbers on the cubes is 7, Hannah wins. If the sum is not 7, Corrine wins. Corrine says Hannah can win only if the following occurs:1 on the first cube, 6 on the second cube2 on the first cube, 5 on the second cube3 on the first cube, 4 on the second cubeWhich best explains if Corrine is correct?Corrine is correct because there are only three ways to have a sum of 7 when the cubes are rolled.Corrine is correct because there are no 7s on the cubes, so Hannah must roll a greater number on the second cube.Corrine is not correct because Hannah can also roll doubles on the cubes, such as 3 on the first cube and 3 on the second cube or 4 on the first cube and 4 on the second cube.Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.

Accepted Solution

A:
D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second. Step-by-step explanation: To get a sum of 7 by rolling two cubes, we need to get one of the combinations from the list below: 1 on the first cube, 6 on the second cube or 6 on the first cube, 1 on the second cube 2 on the first cube, 5 on the second cube or 5 on the first cube, 2 on the second cube 3 on the first cube, 4 on the second cube or 4 on the first cube, 3 on the second cube Therefore, the correct answer option is D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.
