Question: 4 wires (red, green, blue, and yellow) need to be attached to a circuit board. A robotic device will attach the wires. The wires can be attached in any order, and the production manager wishes to determine which order would be fastest for the robot to use. Use the multiplication rule of counting to determine the number of possible sequences of assembly that must be tested. (hint: there are 4 choices for the first wire, 3 choices for the 2^nd wire, 2 choices for the 3rd wire, and only one for the 4^th wire.
