Dice Probability Problems for Quant Interviews

Dice problems test your ability to think systematically about sample spaces, expected values, and geometric distributions — core skills assessed at every major quant firm.

Sample Problem

You roll two fair six-sided dice. What is the expected value of their sum?

Answer: 7 (using linearity of expectation: E[die 1] + E[die 2] = 3.5 + 3.5 = 7)

This is one of several detailed problems covered in our complete guide, including geometric distributions and systematic counting techniques.
