Threshold Five Sixths Counts - Precision and Recall, Exactly

Count the confusion cells at threshold five sixths.

highlighted = computed this step

Move to threshold five sixths

At threshold 5/6, only A is on or above the marker.

t=5/6

The grid is TP=1, FP=0, FN=2, TN=2.

(TP,FP,FN,TN)=(1,0,2,2)

The row scores and true labels stayed fixed. Only the stated threshold changed.
