Complete Git Guide: Understand and Master Git and GitHub - More details on hash collision probability (OPTIONAL)

The lecture delves into hash collision and probability theory, correcting previous misconceptions about hash collisions. It uses dice games to explain probability concepts and extends these ideas to understand the probability of hash collisions in Git repositories. The lecture concludes with a formula to calculate the probability of hash collisions, emphasizing that such events are extremely rare.

What is hash collision and how does it occur?

Explain the probability of producing the same exact hash for different files.

How does the probability of getting the same number on two dice relate to hash collisions?

What is the formula for calculating the probability of getting the same number on N dice?

Describe the process of calculating the probability of all different numbers on multiple dice.

What is the significance of factorials in calculating probabilities in this context?

Explain the relationship between the number of dice and the probability of getting at least two same numbers.

How does the number of files in a repository affect the probability of hash collisions?

What is the probability of hash collision when the number of files exceeds 2^160?

What insights can be drawn from the calculations regarding hash collision probabilities in Git repositories?
