The probability of rolling a number greater than 20 is 0.
Solución
Step 1: List the outcomes of rolling the die
The possible outcomes are:
The possible outcomes are:
Step 2: Identify the favorable outcomes
We are looking for outcomes where the number is greater than 20. Since every outcome is less than or equal to 12, there are no outcomes that are greater than 20.
We are looking for outcomes where the number is greater than 20. Since every outcome is less than or equal to 12, there are no outcomes that are greater than 20.
Step 3: Calculate the probability
The probability is given by:
The probability is given by:
Since there are 0 favorable outcomes, we have:
Thus, the probability of rolling a number greater than 20 is

Simplifique esta solución Beyond the Answer
When rolling a 12-sided die, the possible outcomes are limited to the numbers 1 through 12. Since all these numbers are less than 20, there are no outcomes that satisfy the condition of rolling a number greater than 20.
Therefore, the probability of rolling a number greater than 20 is
