# What is the probability of the sun setting tomorrow?

**Solution:**

We have to find the __probability__ of the sun setting tomorrow.

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

The event that is certain to happen is called a Sure event or certain event.

The sun sets every evening.

So, it is a Sure event.

We know that the probability of an event that is certain to happen is 100% or 1.

Therefore, the probability of the sun setting tomorrow is 1.
