exam score is like considering the sum of ten draws with replacement from the box with ten tickets worth 4 points each and 5 tickets worth 0 points. Each draw represents Jason's attempt at answering a question, with the box containing tickets representing correct and incorrect answers. The probability of drawing a correct answer ticket is 1/5, as Jason has an equal chance of choosing the right option for each question.
The simulation reflects the random nature of his guesses, with correct answers contributing 4 points to the total score, and incorrect answers contributing 0 points. By repeating this process for all ten questions, the simulation models the variability in Jason's possible exam scores based on random guessing.
