There is a typo for #27. The correct answer should be 3, not 1.

Is this better?  Thanks.


There are 4 balls labeled 1, 2, 3, and 4, respectively, in a box. Randomly take out two balls and the positive difference of the numbers on these two balls is x. What is the most possible value of x?

I see what the question means now. The following will read even better:
"What is the most popular value of x?" Or
"What is the mode of all values of x?"
