What is 16

100

This is the symbol for a conjunction

What is the dot?
200

A logical operator that is true when at least one of the propositions is true

What is a disjunction?

200

This is another word for a proposition

What is a statement?

200

This is a proposition that is false by logical structure.

What is a self-contradiction?

When using a shorter truth tale for determining validity you need this many rows

What is one?

200
This is the symbol for a disjunction

What is the vee?

300

What is a biconditional?

300

This represents a single proposition and is typically symbolized with a capital letter

300

If a propositions has true premises and a false conclusion then it is this.

What is invalid?

300

Use a shorter truth table to determine the validity of the following proposition:


If S then I, If S then Y, therefore I or Y

What is invalid?

300

Symbolize the following proposition:

If you study then you will pass the test, if you don't study then you will do something fun, therefore you will either pass the test or do something fun
