A bank vault has three locks with a different key for each lock. Each key is owned by a different person. To open the door, at least two people must insert their keys into the assigned locks. The signal lines A, B, and C are 1 if there is a key inserted into lock 1, 2, or 3, respectively. The output variable Z which is 1 iff the door should open. Write an equation for the scenario above. List the assignment for each variable. Write its equivalent truth table showing each term.
