Suppose we have the following statements
- Sun rises from the west
- Ganga is the river in India
- 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
