Question

How many rows appear in a truth table for the compound proposition:

(p↔q)⊕(¬p↔¬r)∧¬q

Answer 1

you have 3 variables, each with 2 truth values (TRUE/FALSE)

Answer 2

what do you mean true or false?

Answer 3

total rows = \(2^3\)

Answer 4

i suppose that's true...if you ignore the negations...do you?

Answer 5

they're asking for rows, not columns.
rows depend only on number of variables. they dont depend on what the expression is

Answer 6

i see. i see. and columns do?

Answer 7

thats right, columns depend on expression. but its entirely upto you how many columns you want to show in a truth table
