Final answer:
The 155 Block Plan is a mathematical concept used to study the probability of different paths people take when walking in a city. It involves analyzing patterns in pedestrian movement and determining the likelihood of two people ending up at the same destination using different routes.
Step-by-step explanation:
The 155 Block Plan is a concept in mathematics that represents the different possible paths people can take when walking in a city. The blocks in this plan are all 120 meters on a side, and the numbers 155 refer to the number of blocks in the plan.
By analyzing this plan, mathematicians can study the probability of different paths being taken and analyze patterns in pedestrian movement within the city.
For example, they can calculate the likelihood of two people randomly starting at different locations and ending up at the same destination using different routes.
