Chapter 19: Probability

1. Give an example to explain how probability is really about prediction.
2. Why might the term likely that we use to describe a probability cause difficulty for some students?
3. A student says that the probability of rolling a 3 on a die must be 3/6, but the probability of rolling a 4 must be 4/6. How would you respond?
4. How can you link probability work to number or geometry work?
5. A student rolls a 2, 2, 3, 4, 2, 2. He says that it will be 3, 4 next since there was 3, 4 after the last 2, 2. How would you respond?
6. How might cultural or societal beliefs interfere with a student’s understanding of probability concepts?
7. Why might a student think that the probability of flipping a head and a tail would be 1/3 if tossing two coins? How could you convince him or her it is not?
