Final answer:
The percentage of getting a 2, 4, or 5 when rolling a standard six-sided dice is 50%.
Step-by-step explanation:
In a standard six-sided dice, there are 6 possible outcomes: {1, 2, 3, 4, 5, 6}. We are interested in the outcomes 2, 4, and 5. These outcomes occur 3 out of the 6 possible outcomes, so the probability of rolling a 2, 4, or 5 is 3/6 or 1/2. To find the percentage, we multiply the probability by 100. So, the percentage of getting a 2, 4, or 5 when rolling the dice is 50%.
