Computational and Critical Thinking Questions 1. [150:5 Because a Boolean function of n variables has only 2n possible combinations of input values, the function can be completely described by giving a table with 2n rows, each row telling the value of the function for a different combination of input values. Such a table is called a truth table.] The table in the image titled Figure 3-3 (2-input version of majority function) shown above is a simple example of a truth table that defines a simplified version of the 3-input majority function found in Figure 3-3 on page 151 of the textbook. The textbook 3-input truth table contains 8 rows: Why are there only 4 rows in the simplified 2-input version
