KAKURAKU vs Computer Networking Basics

KAKURAKU is an interactive educational app for experiencing probability paradoxes through hands-on simulation. The 10th installment in the SUUGAKU / BUTURAKU / DENRAKU / HARAKU / NETURAKU / KORAKU / RYURAKU series. The theme is "probability." Experience 12 famous probability paradoxes through four interactive phases. [4 Phases for Deep Understanding] 1. Intuition Quiz Answer with your gut feeling first. Most people get it wrong. 2. Simulation Run hundreds of trials and see the results with your own eyes. 3. Explanation Why does intuition fail? Mathematical explanations bring that "aha" moment. 4. Comprehension Check Test your true understanding with applied questions. [12 Probability Paradoxes] 1. The Door Trap — Monty Hall Problem (switching wins 2/3 of the time?) 2. Miracle Classroom — Birthday Paradox (50%+ chance with just 23 people?) 3. The Gold Box — Bertrand's Box (your 1/2 intuition is wrong?) 4. Reversal Statistics — Simpson's Paradox (parts and whole tell opposite stories?) 5. Envelope Dilemma — Two Envelope Problem (should you always switch?) 6. Test Trap — False Positive Problem (positive result yet only 16% infected?) 7. Sleeping Princess — Sleeping Beauty Problem (1/2 or 1/3? Still unsolved) 8. Endless Bus — Bus Waiting Paradox (average 5 min but you wait 10?) 9. Red Streak — Gambler's Fallacy (black is "due" next?) 10. Infinite Gamble — St. Petersburg Paradox (infinite expected value?) 11. Warden's Verdict — Three Prisoners Problem (does A's fate change?) 12. The Predictor's Boxes — Newcomb's Paradox (one-box or two-box?)
