Concept with Explanation
Selected Homework from ACE
The unit How Likely Is It? was created to help students:
Understand that probabilities are useful for predicting what will happen over the long run
Understand the concepts of equally likely and not equally likely;
Understand that a game of chance is fair only if each player has the same chance of winning, not just a possible chance of winning;
Understand that there are two ways to build probability models: by gathering data from experiments (experimental probability) and by analyzing the possible equally likely outcomes (theoretical probability);
Understand that experimental probabilities are better estimates of theoretical probabilities when they are based on larger numbers of trials;
Develop strategies for finding both experimental and theoretical probabilities; and
Critically interpret statements of probability to make decisions or answer questions.
