Complete Git Guide: Understand and Master Git and GitHub - Probability Theory in a Dice Game

The video tutorial explains the concept of Git file storage and the length of SHA-1 hashes. It then introduces basic probability theory using dice as an example, covering the probability of rolling specific numbers and combinations. The tutorial further explores the probability of different dice combinations and applies these concepts to understanding SHA-1 hash collisions.

What is the length of a SHA-1 hash in bits?

• 256 bits

• 128 bits

• 512 bits

• 160 bits

What is the probability of rolling a specific number with a single die?

• 1/6

• 1/4

• 1/2

• 1/8

If you roll two dice, what is the probability of getting the same number on both?

• 1/6

• 1/12

• 1/18

• 1/36

How do you calculate the probability of rolling two different numbers on two dice?

• Subtract the probability of each number

• Add the probability of each number

• Multiply the probability of each number by 2

• Multiply the probability of each number by 3

What is the probability of rolling a 4 and a 5 on two dice?

• 0.112

• 0.084

• 0.056
