Make up a truth table for the addition of the two inputs. Arrange the selection from the multiplexer to give the correct output.

Use the "select" bits of the 4-1 multiplexor as the inputs of the full adder, then use the 4 different inputs to the mux as the corresponding output for each selected combination.
