Theorem measvuni 33200

Description: The measure of a countable disjoint union is the sum of the measures. This theorem uses a collection rather than a set of subsets of 𝑆. (Contributed by Thierry Arnoux, 7-Mar-2017.)

**Assertion**
Ref	Expression
measvuni	⊢ ((𝑀 ∈ (measures‘𝑆) ∧ ∀𝑥 ∈ 𝐴 𝐵 ∈ 𝑆 ∧ (𝐴 ≼ ω ∧ Disj 𝑥 ∈ 𝐴 𝐵)) → (𝑀‘∪ 𝑥 ∈ 𝐴 𝐵) = Σ^*𝑥 ∈ 𝐴(𝑀‘𝐵))

Distinct variable groups: 𝑥,𝐴 𝑥,𝑀 𝑥,𝑆 Allowed substitution hint: 𝐵(𝑥)
