Answer: The correct option is (B) x = 0.
Step-by-step explanation: Given that, 'x' represents the probability of an impossible event.
We are to select the TRUE statement from the given options.
We know that the probability of happening of an y event lies between 0 and 1.
If an event is sure and certain, then its probability is 1.
If an event is impossible, then its probability is 0.
Since 'x' is the probability of an impossible event, so its value must be 0.
Thus, x = 0.
Option (B) is correct.
