Theorem: Probly.Rand.pure_E (Probly/Rand.lean)

State before:
X : Type
inst✝⁸ : MeasurableSpace X
Y : Type u_1
inst✝⁷ : MeasurableSpace Y
Z : Type ?u.21067
inst✝⁶ : MeasurableSpace Z
inst✝⁵ : NormedAddCommGroup X
inst✝⁴ : NormedSpace ℝ X
inst✝³ : NormedAddCommGroup Y
inst✝² : NormedSpace ℝ Y
inst✝¹ : NormedAddCommGroup Z
inst✝ : NormedSpace ℝ Z
x : X
φ : X → Y
⊢ E (pure x) φ = φ x
