Document Summary
Chapter one: for the truth table, go to http://turner. faculty. swau. edu/mathematics/materialslibrary/truth/ and type in ~(a&(b+~c)) for the boolean expression and hit generate table. A truth table will have 2 to the power of x rows, where x is the number of letters/variables you are using. (a+b)&(a+c) for the right: if b1,b2, ,bn are mutually exclusive, then only one of them can be true at one point in time. Now, in a conjunction (eg a^b1), if any term is false, then the whole conjunction is false. So, if only one of b1 through bn can be true at any point in time, then all but one are false at the point in time. It follows then that all but one of the conjunctions a^bx (where bx will just be the whole set of b1 through bn) must be false when any single sentence in bx is true. For example, if b1 is true, b2 through bn is false, and therefore.
