Section 1

The Roll of two dice.

To start us down that road, consider the following question given below.

Value: 1

Let sentence 1 (call it p), be, "I have rolled a pair of dice and added the numbers together and they add up to 12", and let sentence 2 (call it q), be the statement, "both dice show sixes"


If p is true, then q must also be true.



Was your answer correct? If not, do you understand why?

The process of looking at information, and drawing conclusions from that information invites us to examine relations between statements, and our primary question for the next few sections will be to learn how to determine whether the truth of one statement affects the truth of another statement, and when it does, what accounts for that relationship.
