Frage 101

A standard fair six-sided die is rolled once. Select all statements that are true about rolling an even number. Select all that apply.

  1. Three of the six faces show an even numberRichtige Antwort
  2. The probability is 2 out of 6, because only 2 and 4 are even
  3. The probability is 3 out of 6, or one half once the fraction is reducedRichtige Antwort
  4. The probability is 1 out of 6, because even counts as a single outcome

Erklärung

The faces 2, 4 and 6 are even, so three of the six equally likely faces succeed and the probability is 3 out of 6, which reduces to one half without changing its value. Stopping at 2 and 4 forgets the face 6, and treating even as a single outcome ignores that the event is made of three separate faces the die can land on.
