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 there is a 100 % chance that the temperature will be less than 120^(∘)F tomorrow. Let's mark the 100 % chance on our diagram!
Looking at the diagram, we can see that the 100 % chance represents the probability of 1. In this case, it is certain that the temperature will be less than 120^(∘)F tomorrow.
