18 August 1913 ko Monte Carlo mein black lagataar 26 baar aaya. Lagbhag pandrahvein black ke baad se players table par toot pade, red par bet lagate rahe kyunki woh “due” tha, aur laakhon francs haar gaye. 26 blacks ki probability (18/37)²⁶ hai, lagbhag 137 million mein ek; kisi na kisi ko, kahin na kahin, kabhi na kabhi yeh dikhne ki probability ek thi.
Sawaal
Nahi. Har ek ke 18 numbers.
Table behavior ki zyadatar published studies mein thode se margin se red. Isse kuch nahi badalta.
Haan, bilkul. Layout par woh bikhre lagte hain kyunki layout ginti ke order mein hai.
Thodi hansi
Wheel ki koi memory nahi hoti. Players ki zaroorat se zyada hoti hai.
