Constingency Table: Probability
A survey of 200 students showed the following:

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}

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