# The probability of an event which is impossible to happen is _________. Fill in the blanks to make the statement true.

**Solution:**

Given, the probability of an event which is impossible to happen is _________.

We have to fill in the blanks to make the statement true.

__Probability__ defines the likelihood of occurrence of an event.

Probability can be defined as the __ratio__ of the number of favorable outcomes to the total number of outcomes of an event.

An event with no chance of occurring is known as an impossible event.

Example: Find the probability of finding a letter X in the word “MAD”

Probability = Total number of favourable outcomes / Total number of possible outcomes

Possible outcomes = M, A, D

Total number of possible outcomes = 3

Total number of favourable outcome = 0

Required probability = 0/3 = 0

Therefore, the probability of an event which is impossible to happen is 0.
