# Q2, W7: January 5th – 8th Advanced Math Teacher Felicia Taylor Advanced Math 7th 16 Focus 4: Probability
Standard(s) Taught

#### Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.

1. Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.
2. Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.
Learning Targets and Learning Criteria

Students are successful when they can…

• understand that probabilities are numbers from 0 to 1.
• understand that the probability of 1 is certain and 0 is impossible.
• justify the categorization of events as likely, unlikely, equally likely, or neither likely non unlikely and use appropriate vocabulary.
• conduct simple experiments and calculate probabilities
• explain the difference between experimental and theoretical probability using appropriate vocabulary and examples.
• collect date on chance events and approximate the relative frequency of an event given the probability.
• use variability to explain why the experimental probability will not always exactly equal the theoretical probability.
• calculate simple probabilities of events
• create a uniform probability model ( a situation in which all outcomes are equally likely)
• compare the results of trials and draw conclusions
• compare / contrast uniform vs. non uniform probability models
