please help me with this problem for multism!!

3. A parity bit is used for the purpose of detecting errors during transmission of binary data. A parity bit is an extra bit included with a binary message to make the number of l's either odd or even. Design and build a 3-bit odd parity generator. The parity generator circuit will take 3 input bits, x, y, and z, and produce 1 output bit, P. a. Obtain the truth table for 3-bit odd parity generator function P b. Derive the Boolean function for P c. Draw the logic diagram and build the circuit using a single7486 chip
