What this assessment looks like
Expected value and probability under time pressure: dice, cards and urn setups, ranking events by likelihood, and order-of-magnitude estimation questions with no clean closed form.
- Expected value computed fast and used to make a decision
- Conditional probability and Bayes updates without formal notation
- Ranking likelihoods rather than computing them exactly
- Fermi estimation: decomposing an impossible question into three easy ones
Train it here
- Likelihood Ranking - Order events from most to least likely - the exact screen-question format.
- Fermi Estimation - Piano tuners in Chicago, atoms in a body - scored on order of magnitude.
- Quitters Never Lose - A casino stopping-strategy game that is secretly a martingale lesson.
- Tail Risk - Rare events and fat tails - where naive expected value goes wrong.
