This all hinges on when you count the number of problems you have. But that's why you have two eyes! Read the same page of books 1 and 2 in parallel and obliterate 100% of your problems.
I disagree. If one book solves half of your problems at random and the other does the same, that's still 75% on average, and 25% on average will have 2 solutions.
