Where an extractor requires that every event gets the same probability under the [[uniform distribution|0AREFQ9Z65]] and the extracted distribution, only the latter is required for a disperser. So for a disperser, an event $A \\subseteq \\{0,1\\}^{m}$ we have: $Pr_{U_{m}}[A] \u003e 1 - \\epsilon$\n",
