I'm confused about how to set it up correctly and how to complete it.

"Out of 40 students"  --  that's your total-total; put that into the lower-right-hand box

 

"14 are taking calculus"  --  that's the total for the "taking calculs" column; put that in.

 

Now, you can find the total for all those "not taking calculus"

 

"29 are taking biology"  -- that's the total for the "taking biology" row; put that in

 

Now, you can find the total for all those "not taking biology"

 

5 are taking both"  -- that fills in the box for those that are taking both calculus and biology; put that in.

 

Now, you can complete the table ...
