This is like the trick question:
Q: "Seven months of the year have 31 days, how many have 28 days?"
A: Twelve! They all have 28 days. The question doesn't say "ONLY 28"
or "EXACTLY 28". It just says "28".
Similarly,
Q: Six marbles are in a basket. Six children each take one marble. But there
is still one marble left in the basket. How can that be?
A: There are 7 marbles in the basket. The question doesn't say "ONLY six
marbles" or "EXACTLY six marbles" It just says "six marbles". If there are
seven in there, there are also six in there. If you had $7 and somebody
asked you if you had $6 would you say no? Of course not. It's the same
principle.
