pure chance, all of the red apples happen to be wormy, while at least some of the yellow apples happen not to be wormy. i pick up an apple from the pile. the apple happens to be red.
if the apple i have picked up from this pile is red, that apple is wormy.
the statement is true, at least for a particular stretch of time, because any apple i pick up from the pile will be wormy should it happen to be red. during that stretch of time, the apple from that particular pile will be wormy if it is red. maybe later someone will throw in a non-wormy red apple,
