Why not answer choice "D" = 5 in the last question? That also makes answer positive.

LOL I thought the same thing. The example has 2 possible answers.

Pardeep and D from the D -

So glad you caught that.... We're going to fix it. We have over 6,000 practice items so invariably we have to correct errata from time to time.

We've embedded another video above for your viewing for the meantime.

Thanks!
