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.

Hi George,Y;

Casella's probability textbook,

Which one?

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

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