To solve this question we will use the following formula to get the theoretical probability:
Now, notice that the possible outcomes of rolling a die are 1, 2, 3, 4, 5, and 6, then the number of total cases is 6. Since we want to compute the probability of getting 1, then the number of favorable cases is 1.
Therefore, the probability of getting 1 when rolling a die is:
Answer: Last option.
