Brian Cox Breaks Down Quantum Mechanics with Feynman's Path Integral Approach!

Feynman path integral formulation of quantum mechanics, which provides a simple rule to calculate the probability of a particle moving from one location to another. This approach considers all possible paths the particle could take, and assigns a probability to each path based on the 'action' - a quantity related to the particle's mass, time, and distance traveled.

totally didnt understand nothing of it and still enjoyed hearing it

The question is then, what makes a partical (choose) sometimes for the lowest propability and why?
