Answer: Certain
Step-by-step explanation:
Probability is the study of chance behavior. The sum of the probabilities of all possible outcomes should add up to 1. This is a fundamental law of probability. If the sum of the individual probabilities is 1, it means that one of these outcomes is certain to occur each time an experiment is conducted. In the context of this question, we're told that the sum of the probabilities of Clara choosing a dot tile, a wind tile, or a dragon tile is 1. This can mean only one thing - Clara is certain to choose one of these 3 types of tiles each time she chooses.
