Detailed Solution

A probability of an event reflects the chance or likelihood that a particular event will occur.
The probability of an event can be calculated as: $\frac{Number of favourable outcomes of an event}{Total possible outcomes of an event}$
Probability can range from 0 to 1.
A certain event is one that will definitely occur. That means all the possible outcomes are favourable. Hence the probability of the event will be maximum which is 1.
For example, an event of receiving a number less than seven when a dice is rolled is a certain event with probability 1.

Therefore, we can say that the probability of a certain event is 1.
