We know that (AND, OR, NOT] is a functionally complete set. In the lectures we showed that (NAND] is a functionally complete set by showing how AND, OR and NOT can be implemented only with NAND gates. Similarly, we showed that (NOR) is a functionally complete set. Using a similar strategy, a) b) Show that (OR, NOT) is a functionally complete set. Show that (AND, NOT] is a functionally complete set
