Little practice before the example

Hello, I am currently practicing what we just went over in this lesson (the part right before the example questions start) and I am a little confused on the conclusion for example #2. It goes : P: T most S P: T -> R Both rule #1 and rule #2 are satisfied therefore a conclusion is possible. While the right conclusion to draw is: S-s-R, I am wondering how this other conclusion is not correct. C: R most S, I know it does not follow the rules we went over but it makes sense looking at the diagram. S S S S S S T T T T T R R R R R If most Ts are S and all Ts are R then accordingly most Rs are S (R m S), no?

Nvm!!! I realized that "all" statements are not reversible therefore all Ts might be R but not all Rs are T

That's right - the only inference we can make is ~R -> ~T.
