The probability of an impossible event is 0 because it cannot occur in any situation.

In general, probability ranges from 0 to 1.

0 implies that the event is an impossible situation and 1 represents an event to occur for sure.

Example: Getting a number 7 while rolling a die is an impossible event with 0 probability. (Since, a die has numbers ranging from 1 to 6)

### Thus, the probability of an impossible event is 0.
