Theorem probmeasb 33418

Description: Build a probability from a measure and a set with finite measure. (Contributed by Thierry Arnoux, 25-Dec-2016.)

**Assertion**
Ref	Expression
probmeasb	⊢ ((𝑀 ∈ (measures‘𝑆) ∧ 𝐴 ∈ 𝑆 ∧ (𝑀‘𝐴) ∈ ℝ⁺) → (𝑥 ∈ 𝑆 ↦ ((𝑀‘(𝑥 ∩ 𝐴)) / (𝑀‘𝐴))) ∈ Prob)

Distinct variable groups: 𝑥,𝐴 𝑥,𝑀 𝑥,𝑆

Proof of Theorem probmeasb Dummy variable 𝑦 is distinct from all other variables.
