Exercise 31 Page 289

Use the diagram that relates the likelihoods and probabilities.

Certain, see solution.

Practice makes perfect
We want to describe the likelihood of the given event. We can recall that the probability of an event is the number between 0 and 1 that represents the likelihood that the event will occur. We also know that the diagram relates the likelihood, above the diagram, to the probabilities listed below the diagram.

We know that the probability that the sun rises tomorrow is 1. Let's mark this number on our diagram!

Looking at the diagram, we can see that the probability of 1 represents a 100 % chance that the sun rises tomorrow. In this case, it is certain that the sun will rise tomorrow.
