We are asked to determine the expression that represents the probability of the union of not A and not B. If we represent not A and not B as:


\begin{gathered} \text{not A = A'} \\ \text{not B = B'} \end{gathered}

The union is represented as:


A^(\prime)\cup B^(\prime)

And if we want to represent probability we use:


P(A^(\prime)\cup B^(\prime))

And thus we get the representation.
