(x XOR y)' = (xy'+x'y)' = (xy')'(x'y)' = (x'+y)(x'y)' = (x'+y)(x+y') = x'x+x'y'+yx+yy' = 0+x'y'+yx+yy' = x'y'+yx+yy' = x'y'+yx+0 = x'y'+yx = xy+x'y' = xy + (x+y)'

You are given a boolean expression consisting of a string of the symbols 'true', 'false', and', 'or', and 'xor'.
[III.4] You are given a boolean expression consisting of a string of the symbols 'true', 'false', and', 'or', and 'xor'. Count the number of ways to parenthesize the expression such that it will evaluate to true. For example, there is only 1 way to parenthesize 'true and false xor true' such that it evaluates to true. Complete the following tasks. [III.4a] Show the parenthesization of the example such that evaluate to true. 'true and false xor true' [III.4b] Show the optimal substructure...
