Why is quiz part often harder than content in a maths textbook?

I find many problems very very tough to do in Casella's probability textbook, which reveals knowledge not covered in his content.

It seems a convention that maths teachers leave the hardest part in problems.

Unfortunately I am not a guy relying on answer manuals.

Geeeeeeeeeeeeeeeeee!

Hi George,Y;

Casella's probability textbook,

Which one?

I am forced to agree. I have seen some where the problems are undoable even if you are familiar with the chapter.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
