Title: Using Probability in Search-and-Rescue Operations | Prediction by the Numbers
URL: https://aptv.pbslearningmedia.org/resource/nvpn-sci-sarops/using-probability-in-search-and-rescue-operations-prediction-by-the-numbers/
Description:

Explore how probability can be used to help find people lost at sea, even when rescuers have very little information, in this video from NOVA: Prediction by the Numbers. To improve its search-and-rescue efforts, the U.S. Coast Guard has developed a system that uses Bayesian inference, a mathematical concept that dates back to the 18th century. The Search and Rescue Optimal Planning System (SAROPS) uses a mathematical approach to calculate probabilities of where a floating person or object might be based on changing ocean currents, wind direction, or other new information. Use this resource to stimulate thinking and questions about appropriate uses of statistical methods.

Description:

This interactive teaches and provides practice in the identification of odds, the conversion of odds to probabilities and probabilities to odds, and the comparison of odds and probability events. This game is recommended for grades 9 -12.

Title: Precalculus and Advanced Topics, Module 5, Topic C: Using Probability to Make Decisions
Description:

Module 5, Topic C is a capstone topic for this module, where students use what they have learned about probability and expected value to analyze strategies and make decisions in a variety of contexts (S.MD.B.5a, S.MD.B.5b, S.MD.B.6, S.MD.B.7). Students use probabilities to make a fair decision and explain how to make fair an “unfair” decision. Students analyze simple games of chance as they calculate and interpret the expected payoff in context. They make decisions based on expected values in problems with business, medical, and other contexts. They also examine and interpret what it means for a game to be fair. Interpretation and explanations of expected values are important outcomes for Topic C.

Note: This module is identified as Precalculus and Advanced Topics in the EngageNY curriculum. It also corresponds to the Algebra II and Algebra II with Trigonometry Alabama Courses of Study.
