Total: 150

Job: 93

Driver's license: 128

Both: 76

We construct the table:

Now, using the fact that the total is 150, from the last row:


\begin{gathered} 128+17+y=150 \\ y=5 \end{gathered}

And from the last column:


\begin{gathered} 93+52+y=150 \\ y=5 \end{gathered}

Finally, the complete table is:
