Would it be easier to guess a number between 1 and 5 or between 1 and 10?

Answer 1

Unless you're a very indecisive personality, the ease or difficulty of picking a

number shouldn't have anything to do with what size group of numbers you're

asked to pick it out of.

But if you're trying to guess what number somebody else is thinking of, then your

chance of guessing his number between 1 - 5 correctly is double the chance of

guessing his number between 1 - 10 correctly.

Between 1 - 5: Your chance of guessing his number is 20%, or 4 to 1 odds against.

Between 1 - 10: Your chance of guessing his number is 10%, or 9 to 1 odds against.
