Add, subtract, multiply, or divide two integers

Add, subtract, multiply, or divide two integers

What you'll learn

  • Calculate expected values for various probability scenarios involving discrete and continuous random variables with at least 80% accuracy.
  • Analyze different betting strategies by comparing their expected values and variances, and justify which strategy is optimal given specific risk preferences, as measured by a written explanation scoring at least 4 out of 5 on a rubric focused on mathematical justification and clarity.
  • Apply decision-making strategies, such as maximizing expected value or minimizing risk, to real-world scenarios involving uncertainty and probability, and demonstrate the application in a presentation that accurately represents the chosen strategy and its potential outcomes.
  • Evaluate the impact of bias and framing effects on decision-making in probabilistic scenarios, and articulate, in a short essay, how these factors can lead to suboptimal choices, with the essay demonstrating a clear understanding of at least two distinct biases.
