TitleNight session, Pascal's identity, clip 4 of 7: An example of Pascal's identity
PublisherNew Brunswick, NJ: Robert B. Davis Institute for learning, , c1999-05-12
Persistent URLhttps://doi.org/doi:10.7282/T3BR8S27
DescriptionThis is the second of seven clips from the night session. In it, Jeff, Michael, and Romina, along with Ankur (who has just arrived), use the analogy they call “people on a line” to investigate the meaning of 3!, which they indicate means 3 times 2 times 1. When asked to explain “why you multiply,” Ankur responds by making use of the different analogy of counting the number of ways to arrange three different colors.
