Construct a truth table for the following Boolean expressions a. (5 pts) AB AC 11.1 ABC Note how the table is built: first with the base variables, A, B, and C, then A, B, and C, and then the combinations that appear in the equation. Your last column is the full equation A B C A B C AB AC ABC AB+AC+ABC b. (8 pts) (YZ +YZ)X For this second part, there are 9 columns needed to build up from the individual variables to the final equation. Fill the first 8 in; the 9th is completed for you. Then complete the table
