state two events such that one has probability 0 and the other has probability 1 give reason and support your answer with an example

I hope this answer will help you.
For probability to be zero.
Eg:Probability of getting a number greater than 6 on rolling a dice[No number is greater than 6 on a dice so probability is zero]
For probability to be one.
Eg: Probability of getting an integer from 1 to 6[1,2,3,4,5,6 are the only integers present on a dice so probability is one]
