Question

• there are 12 signs of the zodiac. how many people are needed to guarantee that at least 6 of these people have the same sign?

Answer 1

12 times 5 is 60.5 people would have the same sign with everyone else. The answer is 61.  At 60, every sign could only have 5 people at the worst case scenario. After one more, or 61, one sign has to have 6 people with the same sign.
