Lesson Plan: Vietnam War Draft Probability Exploration

February 9, 2026

Torn remains of a Vietnam War draft card, dated 1972.
By Heather Barker, Elon University

Overview of Lesson

In this lesson, students explore actual data from the 1969 Vietnam War Draft, which was used as a way for the Selective Service to prove to the United States public that the draft was a truly random way to choose who would be chosen to serve. But how truly random was it? In this investigation, students will simulate the way that men were chosen to be drafted and compare the actual results to simulated to results to see how likely what would happen would occur by chance. Students will use simulation, probability, and expected value for this investigation.
