Lawyers overseeing the corruption trial of former state Assembly​ speaker Sheldon Silver picked a jury on Monday.

The 12-person jury includes a retired flight attendant, a retired teacher and a nurse in Mt. Sinai’s critical care department.

The ​re​trial, which kicks off with opening arguments on April 30​,​ is expected to last six to eight weeks.

Silver, 74, is being tried — again — for selling his office in exchange for $4 million in kickbacks.

His 2015 conviction was overturned by an appeals court due to a US Supreme Court’s recent ruling that narrowed the definition of bribery.
