Data Science and Machine Learning (Theory and Projects) A to Z - Expectations: Homework

The video tutorial explains a probability problem involving rolling a four-sided die three times. The focus is on determining the maximum roll, with the random variable having a uniform probability mass function. The tutorial guides viewers through calculating the expected value, variance, and fourth moment of the random variable. The session concludes with a homework assignment to apply these concepts.
