# Each Sign has twelve different possibilities, and there are three signs. What are the odds that any two people will share all three signs? Note: the signs can be in different aspects, but at the end of the day each person is sharing three signs. For example, one person could have Pisces as Sun sign, Libra as Rising and Virgo as Moon sign. The other party could have Libra Sun, Pisces Rising, and Virgo moon.

## Answer

There are twelve possibilities, and each can have three signs = 36 permutations.

But only half of these are a unique combination (e.g., Pisces and Sun is the same as Sun and Pisces)

so that's 18 permutations.

The probability of a person getting one of these arrangements is 1/18

The probability of 2 people sharing all three signs is 1/18 x 1/18 = 1/324
