Need help!!

Four bits (binary digits) can represent decimal numbers from zero through 15. For example, 1101 represents 13. We want to design a circuit with an LED at the output. The LED shoul light up (the output is TRUE or HIGH 5V) for all input combinations EXCEPT the decimal numbers 4, 5, 6, and 7 PRE-LAB I. Draw the Truth-Table for the design problem stated above 2. Use Boolean Algebra to simplify the SOP expression for your Truth-Table 3. Use only TWO NAND gates to draw your circuit (Yes- It IS possible!)
