MA.8.DP.2.3 · Number Sense and Operations and Probability
Probability predictions ask 8th graders to scale a theoretical probability up to a real number of trials, such as predicting about 50 threes in 300 rolls of a fair number cube. Students also compare a prediction to what actually happened.
FAST items are real-world multiple choice and equation editor questions where students multiply a probability by the number of trials. The trap is answering with the probability itself instead of the predicted count.
