Probability and Fairness in Dice Rolling

The video tutorial explores a dice game where Roberto and Jocelyn decide who dusts their apartment based on the sum of two six-sided dice. If the sum is 7, Roberto dusts; if it's 10 or 11, Jocelyn dusts. Otherwise, they roll again. The video demonstrates creating a probability table for all possible outcomes and calculates the probabilities for each scenario. It concludes that the game is not fair, as Roberto has a higher probability of dusting than Jocelyn.
