HSS.MD Tutor Intake - Random Variables, Expected Value, and Decisions
This short diagnostic helps your tutor see where to start in the Using-Probability-to-Make-Decisions unit. Every topic here is advanced (STEM-track) material, so a few items assume you have opted into it. Answer each question on your own, without help. If you are unsure, give your best attempt - a wrong answer still tells your tutor what to review.
