Explain two ways by which the calendar meets or fails to meet the criteria of showing the correct data

The two ways the calendar meets the criteria of showing the correct date are;

1) The calendar can give dates in the 12 months in a year

2) The calendar can show up to the 31 different days in a month

Explanation:

The two ways in which the calendar meets the criteria of showing the correct date are;

1) The number number of long blocks with 4 different months each = Three

Therefore, the total number of months the blocks can hold = 3 × 4 months = 12 months = The number of months in a year

2) The number of faces on each dice = 6 faces

The number of dice = 2 dice

The total number of faces = 12

The number of identical faces = 2 (11th and 22nd of the month)

The number of unique faces = 10

The number of combinations of the dices = ₁₀C₂ = 45

The number of combination of faces required to show = 1 to 31 = 31 combination

Therefore, there are adequate combinations on the dice to show all the dates of month
