Chapter 3.2, Problem 50E

Applying What You’ve Learned

Use the following graph that summarizes the status of couples five years after they decide to live together to find the truth values of the statements in Exercises 49-52. Let p represent the statement “Couples who considered living together as a step toward marriage were most likely to married after five years.” Let q represent the statement “Couples who considered living together as a substitute for marriage were most likely to be split up five years later.” Let r represent “More couples who used living together as a substitute for marriage were married five years later than who were living together but just dating.”

$\sim \left(p\wedge q\right)$
