Final answer:
To compute the probability of rolling a 12-sided die and getting a number other than 8, you divide the number of favorable outcomes by the total number of outcomes.
Step-by-step explanation:
To compute the probability of rolling a 12-sided die and getting a number other than 8, we first need to determine the total number of possible outcomes of rolling the die, which is 12. Out of these 12 outcomes, there is only 1 outcome of rolling an 8. Therefore, the number of favorable outcomes is 11. To calculate the probability, we divide the number of favorable outcomes by the total number of outcomes:
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 11 / 12 = 0.917 (rounded to three decimal places)
