Please help me with part C

2. Congratulations! You have been hired as a summer intern for Family Interactive, a company that specializes in electronic board games that are fun for the whole family. The first game you will work on uses four push buttons to determine the winner. Each of the four switches are assigned a value as shown on the next page. When the buzzer sounds, the first player to press two or more buttons whose face values add up to an even number wins the round. Your task is to design a circuit that lights an LED if the user succeeds in pressing two or more buttons that add to an even number. a. The first step in digital design is determining the number of inputs required. In this case we have four push buttons, so we have four inputs. If we assign variables to the buttons from left to right, we have: W=1,X=8,Y=7, and Z=9. The second step is to define a truth table. Finish filling in the truth table below. A few rows have been completed to get you started. b. The next step is to find a simplified Boolean equation based on the truth table. Using the Karnaugh map provided find the simplified Boolean equation that describes the truth table found in part a. c. The final step is to draw a circuit based on the Boolean expression. Draw the final circuit below. Don't forget to include the switches and the LED in your diagram
