    What is the total number of possible outcomes in the calendar? - ProProfs

    What is the total number of possible outcomes in the calendar?

    • 14

    • 13

    • 12

    • 11

    Correct Answer
    A. 11
    Explanation
    The total number of possible outcomes in the calendar refers to the number of different ways the days of the week can be arranged. In a standard calendar, there are 7 days of the week. However, since the starting day of the week can vary, there are only 7 distinct arrangements. Additionally, there are 4 different possibilities for the number of weeks in a month (4, 5, 6, or 7 weeks), resulting in a total of 7 x 4 = 28 possible outcomes. However, since there are only 12 months in a year, the total number of possible outcomes is limited to 12. Therefore, the correct answer is 12.

    On how many faces is the solution to the two-cube calendar established? - ProProfs

    On how many faces is the solution to the two-cube calendar established?

    • 31 faces

    • 30 faces

    • 3 faces

    • 7 faces

    Correct Answer
    A. 31 faces
    Explanation
    The solution to the two-cube calendar is established on 31 faces. This means that when the two cubes are arranged in a calendar format, there are a total of 31 visible faces. Each cube has 6 faces, so when they are combined, there are 12 faces that are not visible. Therefore, the solution is established on the remaining 31 visible faces.
