    \begin{gathered}<br />
  P(B) = 1 - P\left( {\overline B } \right) \hfill \\<br />
  P\left( {A \cap B} \right) = P(A)P(B) \hfill \\<br />
  P\left( {A \cup B} \right) = P(A) + P(B) - P(A)P(B) \hfill \\ <br />
\end{gathered}

    Thanks Plato. That is the answer I put down. What originally threw me was the line over the B. Common sense took over and what you sent is what I had put down. Still, I was unsure until your confirmation. Appreciate the help.
