MGMAT Word Translation Overlapping Sets Question #14

[nelvin898]

Ill really appreciate it if somebody can explain to me how to do this :)

The 38 movies in the video store fall into 3 categories: 10 action, 20 drama, 18 comedy. Some are classified in multiple categories.

5 are both and action and drama
3 are both action and comedy
4 are both comedy and drama

How many action drama and comedy are there?

TY
