Activity Overview
In this activity, students explore longest the streak for 7 tosses of a coin. They understand the relationship between relative frequency and Theoretical probability. They will be able to clear misconceptions about probabilities of streaks.
Before the Activity
Install the Probability Simulation Application on the calculator using one of these two methods:
- TI Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
- TI-Navigator™ "send to class" feature
- Load the program STREAKS on the calculator
- See the attached PDF file for detailed instructions for this activity
- Print pages 83 - 96 from the attached PDF file for your class
During the Activity
Distribute pages to your class.
Follow the Activity procedures:
Distribute pages of the worksheet
Explore responses to probability questions
Start the Probability Simulation application
Use a simulator to gather data for 30 sets of 7 tosses of a coin
Use the STREAKS7 program to collect data on 500 trials of 7 tosses of a coin
Compare the results with the list of possible combinations
Understand the different predictions, experimental results, and theoretical analysis
After the Activity
Students will complete the Student Worksheet and answer questions.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
