Suppose we have the following statements

  1. Sun rises from the west
  2. Ganga is the river in India
  3. India will win the test match

Statement 1 is always false,

  as Sun rises from east

 

It is an impossible event

So, it’s Probability = 0

 

Statement 2 is always true.

as Ganga is a river in India

 

It is a certain event

So, it’s Probability = 1

 

Statement 3 is not always true or false.

India can win the match or not. Both are possible.

 

Hence, it is neither impossible, nor certain

So, probability will lie between 0 & 1
