| Oct 7, 2017 at 11:23 | comment | added | SmallChess | @farheen I merely followed the formula. 60+10+20+80 = TN for label A. | |
| Oct 7, 2017 at 11:21 | comment | added | farheen | I do understand the denominator which is N and in numerator 30 + 60 + 80 are examples that were classified correctly, can you explain 10 + 20 in numerator? | |
