@ThomasKruza Yes! That is incorrectly understanding the first set of conditions. Play for NFL --> strength + speed + athleticism.

The accurate contrapositive of this is ~strength or ~speed or ~athleticism --> ~play for NFL.

@guppygrr Thank you for your response! Appreciate your language around this example!

So, if I'm understanding correctly... if the statement instead was "Students are cited as 'late' IF they arrive more than 5 minutes past the last ring of the homeroom bell," then this would read in lawgic as 5+ min late --> cited as late. And in that case, then Kumar would be cited as late? The "ONLY IF" is what places the statement following the 'only if' in the necessary vs the sufficient condition?

If I used it in my own example...

"If it is Sunday, I will go on a hike." Reads: Sunday --> Hike.

"Only if it is Sunday, I will go on a hike." Reads: Hike --> Sunday.
