@Narmis The argument isn't valid in your example because being tall isn't necessary for being good at baseball (at least not according to your premise). So while knowing someone is tall is sufficient to know they play baseball, knowing someone plays baseball is not sufficient to know they are tall.

Instead, it would be

T ---> B (if one is tall, they must be good at baseball)

which can be arranged to:

/B ---> /T

so if....

/B ---> /T

and Maia (/B)

then

Maia (/T).
