When you roll a standard six-sided die, there are a total of six possible outcomes: 1, 2, 3, 4, 5, and 6. Each of these outcomes is equally likely.
The probability of a specific outcome can be calculated using the formula:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
In this case, the number of favorable outcomes for getting a 1 is 1 (since there is only one face with a 1 on it), and the total number of possible outcomes is 6.
Plugging these values into the formula gives us:
Probability = 1 / 6
So, the probability of rolling a 1 on a standard die is approximately 0.1667, or 16.67%.
