It begins with an example of a word problem asking how many students passed mathematics based on information about students passing various subjects. The solution uses both a formulaic method and a Venn diagram method. It then discusses basic concepts for solving multi-circle Venn diagram problems, including union, intersection, and the addition theorem for sets.

Word problems involving Venn diagrams
If I work through this step-by-step, using what I've been given, I can figure out what I need in order to answer the question. This is a problem that takes some time and a few steps to solve. They've given me that each of the geckoes had at least one of the characteristics, so each is a member of at least one of the circles. This means that there will be nothing outside of the circles; the circles will account for everything in this particular universe. There was one gecko that was gray, tailless, and chewed on, so I'll draw my Venn diagram with three overlapping circles, and I'll put "1" in the center overlap:

Earlier I provided an "answer" as a hint (in the form of a question). It was deleted as being more appropriate as a comment ("request for clarification") it was not a request for clarification. It was a hint in the form of a question.

"Hint: How many total A's were there out of how many total grades?"

The point is that there were $30+33+37=100$ total A's out of $3\cdot 40=120$ total grades. Hence there were $20$ grades that were not A's. If these grades were maximally spread around among the $40$ students, there would have been $20$ students who got a non A. (There may have been less such students, as some students could have gotten more than one non A.) But in any case that would mean that there are least $40-20=20$ students who got all A's.

Let $x = |A\cap B\cap C|$ be the number of students that got all As.

We use the inclusion-exclusion formula,

$$ |A| + |B| + |C| - |A\cap B| - |B\cap C|-|C\cap A| + |A\cap B\cap C| = |A\cup B\cup C|,$$

to get

$$x = |A\cup B\cup C| - |A| - |B| - |C| + |A\cap B| + |B\cap C|+|C\cap A|$$

To find a bound, we need to bound the intersections: using $$|A\cup B \cup C| \geq |A\cup B| = |A|+|B| - |A\cap B|,$$ we can rearrange to obtain $$|A\cap B| \geq |A| + |B| - |A\cup B \cup C|.$$ Plugging that (and analogous expressions) back into the equality for $x$ gives

$$x \geq |A\cup B \cup C| - |A|-|B|-|C|\\+ (|A|+|B|-|A\cup B \cup C| ) \\+ (|B|+|C|-|A\cup B \cup C| ) \\+ (|C|+|A|-|A\cup B \cup C| ) \\= |A|+|B|+|C| - 2|A\cup B\cup C|.$$

Thus $x \geq |A|+|B|+|C| - 2\cdot40 = 20$, because $40 \geq |A\cup B\cup C|$.
