In Math

Three is the first odd prime number, and the second smallest prime.

  • 1 + 2 = 3
  • 2 + 1 = 3
  • 2 x 1.5 = 3

Lucky or Unlucky

Counting to three is common in situations where a group of people wish to perform an action in synchrony: Now, on the count of three, everybody pull!  Assuming the counter is proceeding at a uniform rate, the first two counts are necessary to establish the rate, but then everyone can predict when "three" will come based on "one" and "two"; this is likely why three is used instead of some other number.

  • In Vietnam, it is bad luck to take a photo with three people in it.
  • Luck, especially bad luck, is often said to "come in threes".
  • Three strikes and you're out.
  • Third time's a charm.

In fictional religion

  • In The Legend of Zelda a divine relic, The Triforce: Wisdom, Power, and Courage, are represented by 3 Golden triangles.
