Problems 26
These problem is designed to get you to look carefully at Example 6.
Problem 27
For each statement in parts a and b, find the corresponding statement in Table 3.7.
For Problems 28-30, first change to symbolic form and then find the corresponding statement in Table 3.7.
Problems 31-38
Read the material in the subsection entitled “CONDITIONAL.”
For example, look at Problem 31, and rewrite “All triangles are polygons.” as “If it is a triangle, then it is a polygon.” Look at the table in the subsection entitled “TRANSLATIONS FOR THE CONDITIONAL” for other translations.

In the givens statement p implies q determine the truth or falsity of p and q, and then use Table 3.6 to determine the truth or falsity of the compound statement.
Problems 43-46
Determine the truth or falsity of p and q for each problem. Then, write down the given symbolic statement, and under each proposition write “T” or “F” as appropriate. Finally, simplify as shown in the symbolic statements at the bottom of Example 5.
Problems 47-52
See Example 5. Be sure to choose a variable for each simple statement (and not for any compound statements).
