NUMB3RS - Season 3 - "Take Out" - Restaurant Ranking
In "Take Out", a series of restaurant invasions turn deadly. The FBI asks Charlie to help, so he develops a predictive model to try to identify the next restaurant that will be targeted. He says that 'it's a way of investigating a group of things -- in this case, restaurants -- and identifying th...https://education.ti.com/en/activity/detail/numb3rs--season-3--take-out--restaurant-ranking
NUMB3RS - Season 3 - "Take Out" - No Fly Zone
In "Take Out", a series of restaurant robberies prompts the FBI to ask Charlie to help predict the restaurant most likely to be targeted next. Charlie says that it can be thought of like a spider catching its prey in a web. Even the best constructed web can not catch all insects. There exist regi...https://education.ti.com/en/activity/detail/numb3rs--season-3--take-out--no-fly-zone
NUMB3RS - Season 3 - "Spree, Part II - Daughters" - Galton Board
In this activity, students will study Galton boards. A Galton board is a vertical or inclined board with a series of staggered pins arranged in a triangle. As balls are dropped from the top of the board, they strike the pins and will fall either to the left or to the right and eventually land in ...https://education.ti.com/en/activity/detail/numb3rs--season-3--spree-part-ii--daughters--galton-board
