Theorem hashnzfzclim 43823

Description: As the upper bound 𝐾 of the constraint interval (𝐽...𝐾) in hashnzfz 43821 increases, the resulting count of multiples tends to (𝐾 / 𝑀) —that is, there are approximately (𝐾 / 𝑀) multiples of 𝑀 in a finite interval of integers. (Contributed by Steve Rodriguez, 20-Jan-2020.)

**Hypotheses**
Ref	Expression
hashnzfzclim.m	⊢ (𝜑 → 𝑀 ∈ ℕ)
hashnzfzclim.j	⊢ (𝜑 → 𝐽 ∈ ℤ)

**Assertion**
Ref	Expression
hashnzfzclim	⊢ (𝜑 → (𝑘 ∈ (ℤ_≥‘(𝐽 − 1)) ↦ ((♯‘(( ∥ “ {𝑀}) ∩ (𝐽...𝑘))) / 𝑘)) ⇝ (1 / 𝑀))

Distinct variable groups: 𝑘,𝐽 𝑘,𝑀 𝜑,𝑘

Proof of Theorem hashnzfzclim Dummy variable 𝑥 is distinct from all other variables.
