The literal count of a Boolean expression is the sum of the number of times each literal appears in the expression. For example, the literal count of $$(xy + xz)$$ is $$4.$$ What are the minimum possible literal counts of the product -of -sum and sum -of-product representations respectively of the function given by the following Karnaugh map? Here, $$X$$ denotes “don’t care”

Which function does NOT implement the Karnaugh map given below?

What is the equivalent Boolean expression in product-of-sums form for the Karnaugh map given in fig?
