Answer 1

10 like all 3 genres.

25 like horror and action, so 25-10 or 15 like horror and action but not comedy. Similarly 20 like comedy and horror but not action and 20 like action and comedy but not horror.

75 - 30 - 30 or 15 like comedy alone.

60 - 30 - 25 or 5 like horror alone.

80 - 30 - 25 or 25 like action alone.

150 - 10 -15 - 20 - 20 - 15 - 5 - 25 or 40 don't like any of them.

Can't help you in drawing the diagram tho.
