    Constingency Table: Probability

    A survey of 200 students showed the following:

    130 were business majors
    140 lived in the city
    40 neither lived in the city or were business majors


    This is on my assignment and I'm having trouble making one for it and I can't go no further without it...any help thanks!

    \begin{tabular}{l | c | c | c} & B & B' & \\ \hline C & & & 40 \\ \hline C' & & 40 & \\ \hline & 130 & & 200 \\ \end{tabular}<br />

    Fill in the blanks and use the table to answer whatever questions you've been asked.
