One event has probability 1/6 and another has probability 1/4. Which of the two events is less likely?

Explanation

Cutting a whole into 6 equal parts makes each part smaller than cutting it into 4, so 1/6 is the smaller number and its event happens less often. Judging 1/4 to be smaller because 4 is less than 6 compares the bottom numbers as if they were the fractions themselves, but with equal top numbers a larger bottom number means a smaller share.
