No real surprise.

When my wife was prepping for her pharmacy boards, she bought the APhA's own study manual. On the inside cover they had a weights and measurements table where they proclaimed there were all of 12 ounces to a pound.

I told her that with that little gem right there, one can only wonder what errors were lurking in the main body of the text.

If it didn't have errors you wouldn't have to revise it for next year and you could get away with used books. Where is the money in that?

I'm not going to lie- some textbooks suck.

BUT, the point of learning always has, and will always be to understand the material on an individual level. Even a 90% accurate textbook should be enough to get you there.

It was just the table up front. It's a lot harder to make those kinds of errors in SI units. I just found it amusing that not only did they screw up something that easy to get right, they also put it as one of the very first things you see.

And here's the really messed up question. If the Textbook says one thing, and reality say another, but the same people who made the textbook generate the answer key to the exam; is it better to learn the truth or the "right" answer?

Unfortunately, it said nothing about Troy ounces, Troy pounds, or anything else like that. If they were referring to those, you'd think they'd mark it better. But then, you'd expect them to get measurements right, so it could just as easily have been a really crappy job of constructing a well defined weights and measurements table.

Maybe you should try reading more than the captions. I see the words "pet" and "breeder" and the picture shows pets that typically breed rapidly when left unchecked so I can see how there might be some relevance to topic being discussed.

To be fair, they didn't say what the numbering scheme was or the formula for calculating the final number. There's probably a solution where dice A has numbers 1-6 and dice B has numbers 2,4,7,9,11,11 and the formula is something like A*(A+B). Maybe that's the problem?

Actually, you could have 36 different results, because 6 X 6 = 36.

Assume die 1 is white (W), and die 2 is black(B):

And I totally screwed that up. But a second cube labeled 1-2-3-4-5-7 would have 12 possibilities paired with a 1-2-3-4-5-6 cube.

And this is why when someone asks the "trick question" about whether a pound of feathers or a pound of gold is heavier, you can confidently say that a pound of feathers is heavier. Even crazier... an ounce of feathers weighs less than an ounce of gold. (1 lb Troy 1 ox Avdp)

statistics CSB:

I was told not to take a class taught by Professor Toons because I would learn nothing. His lectures consisted of him writing an impossibly complex problem on the board and then solving it himself.

Instead I opted for Professor Chens class. I get to class and find that Chen can barely speak English, however he knows this and provides excellent written notes of his lecture. No problem. But... some frat boys in the class don't like it, they can't understand him and complain to the COBA dean and demand a new teacher.

3 days later Professor Toons shows up to teach the class. I immediately stand up, walk out and drop the class. I added it back the next semester from 3rd professor and scored an easy A.

The couple people I knew who stuck it out with Toons barely got by with C and Ds.

Except that (1+3), (3+1), and (2+2) all give the result of 4, (1+5), (5+1), and (3+3) all give the result of 6, etc. The number of unique results drops precipitously.

The term "fair number cube" usually presumes that the die is numbered 1-6. If this isn't true then the instructions would have stated otherwise.

But, it wouldn't matter, because the textbook asked "how many total results are possible?" Even if both cubes started with eleventy, the number of total results would remain the same.

I had a math professor who "for the purposes of the class", declared all multiplicative constants to be equal to 1. Other students started freaking out when he just started dropping Pi from equations because it was equal to 1.

I just asked my Pops (who has taught math for longer than I've been alive) about this. He said that the term "fair number cube" presumes that the die are 6 sided, and are numbered 1-6 unless otherwise stated.

Even if this were not the case, the textbook asked, "how many total results are possible?" Even if both dice began with the number eleventy, the total possible results would not be changed.

"The apothecaries' system of weights is a historical system of mass units that were used by physicians and apothecaries for medical recipes, and also sometimes by scientists.[1][2][3] The English version of the system is closely related with the English troy system of weights, the pound and grain being exactly the same in both.[4] It divides a pound into 12 ounces, an ounce into 8 drachms, and a drachm into 3 scruples or 60 grains." -Wikipedia

I can see why a pharmacy study manual might suggest that there are 12 ounces in a pound, but only as historical curiosity.

I think that study guide may have been correct. They're called "Apothecaries' Weights', similar to Troy weights.

There will still only be 11 possible results. All you've done is shift the results from 2 through 12 to 8 through 18.

If you numbered one die 1 through 6 and the other 10 through 60 then you would have 36 possible results. Not sure what you would need to do to get exactly twelve.
