What is the probability that a multiple of two will occur with one roll of a twenty-sided die numbered from 1-20?
20,18,16,14,12,10,8,6,4,2 are the multiples of two on this particular die. Counting them, there are 10. So, 10/20 - 1/2 - is the probability.

To calculate the probability of a multiple of two occurring with one roll of a twenty-sided die, we need to determine the number of favorable outcomes (i.e., the multiples of two) and the total number of possible outcomes.
The multiples of two from 1 to 20 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20. These ten numbers are our favorable outcomes.
Since the twenty-sided die has numbers ranging from 1 to 20, the total number of possible outcomes is 20.
To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes:
Probability = Favorable Outcomes / Total Outcomes
In this case, the probability is 10 (favorable outcomes) divided by 20 (total outcomes):
Probability = 10 / 20 = 0.5 or 50%
So, the probability that a multiple of two will occur with one roll of a twenty-sided die is 0.5 or 50%.
Remember, you can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes.
