Frage 95

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

  1. The event with probability 1/4
  2. Neither, the two probabilities are equal
  3. The event with probability 1/6Richtige Antwort
  4. It cannot be decided without knowing the number of trials

Erklärung

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.
