Japanese: 確率空間 - かくりつくうかん
Probability space

…The probability of the sum event A = A1A2 ∪… is equal to the sum of the probabilities of each event. In other words, P ( A ) = P ( A1 ) + P ( A2 ) +… A set (Ω, B , P ) with this property is called a probability space, and is the place where mathematical discussions are carried out. Here, P is nothing other than what is called a measure in analysis, but it is a special measure such that P (Ω)=1. …
