Lesson 1 often concludes with conceptual questions to ensure students grasp the terminology.
These are two events where one must happen, but they cannot happen at the same time (e.g., rolling a 6 vs. not rolling a 6). The sum of their probabilities is always Example: If there is a chance of winning, the probability of not winning is Scale of Likelihood: 0 (0%): Impossible. 1/2 (50%): As likely as not (e.g., a coin flip). 1 (100%): Certain. Sample Answer Key Scenarios The sum of their probabilities is always Example:
Keep practicing, and soon probability will feel less like chance and more like certainty.
Since there are 6 sides, the probability of rolling a specific number like a "3" is 16one-sixth Sample Answer Key Scenarios Keep practicing, and soon
