105 True or False Questions. 1. An atom is the smallest particle. Answer: False – there are subatomic particles that are smaller. 2. Arachnophobia is the fear of bathing. Answer: False ...
Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes–no questions; each question must be put to exactly one god.
Logical equality (also known as biconditional or exclusive nor) is an operation on two logical values, typically the values of two propositions, that produces a value of true if both operands are false or both operands are true. The truth table for p XNOR q (also written as p ↔ q, Epq, p = q, or p ≡ q) is as follows:
Multiple choice (MC), [1] objective response or MCQ (for multiple choice question) is a form of an objective assessment in which respondents are asked to select only correct answers from the choices offered as a list. The multiple choice format is most frequently used in educational testing, in market research, and in elections, when a person ...
These examples, one from mathematics and one from natural language, illustrate the concept of vacuous truths: "For any integer x, if x > 5 then x > 3." [9] – This statement is true non-vacuously (since some integers are indeed greater than 5), but some of its implications are only vacuously true: for example, when x is the integer 2, the statement implies the vacuous truth that "if 2 > 5 ...
In a video first reported by The New York Times, Lichtman said that he based his prediction on 13 keys or “big picture true-false questions that tap into the strength and performance of the ...
Statement (logic) In logic and semantics, the term statement is variously understood to mean either: a meaningful declarative sentence that is true or false, or. a proposition. Which is the assertion that is made by (i.e., the meaning of) a true or false declarative sentence. In the latter case, a statement is distinct from a sentence in that a ...
Principle of bivalence. In logic, the semantic principle (or law) of bivalence states that every declarative sentence expressing a proposition (of a theory under inspection) has exactly one truth value, either true or false. [1][2] A logic satisfying this principle is called a two-valued logic[3] or bivalent logic. [2][4] In formal logic, the ...
