\( 1 \leftarrow \) What is the probability of an event that is impossible? Suppose that a probability is approximated to be zero based on empirical results. Does this mean that the event is impossible What is the probability of an event that is impossible? \( \square \) (Type an integer or a decimal.)

The probability of an event that is impossible is exactly 0. This means there is no chance of that event occurring, like trying to roll a six on a standard die when the die is flat on the table. It’s a straightforward concept, and it sets the baseline for understanding all other probabilities. Now, just because empirical results show a probability approximating zero doesn't guarantee that the event is impossible. For instance, if we consider very slight phenomena, such as finding a four-leaf clover, the chances are extremely low (close to zero), yet not impossible. Thus, in probabilities, approaching zero is not the same as being zero.
