Friday, October 30, 2026 · Played it? Here's how rare each one really was.
328 volunteers in a Duke University study (PLOS ONE, 2014).
1 in 1.5 people 67.6%
222 of the 328 participants yawned at least once (67.7%).
Fun fact: Older people were less likely to catch a yawn, and the study found no link with empathy, despite the popular idea.
Worldwide estimate from 92 studies of 63,314 people.
1 in 4.4 people 22.6%
A 2015 meta-analysis found 22.63% of people are missing at least one third molar. Women were 14% more likely than men to be missing one.
Fun fact: In a class of 30, expect about 7 people missing at least one wisdom tooth. Across the studies, the rate ranged from 5% to 56%.

All discovered near-Earth asteroids, NASA count as of December 2025.
1 in about 45 asteroids 2.23%
NASA counted 39,123 known near-Earth asteroids, of which 873 are larger than 1 kilometer.
Fun fact: Lower the bar to 140 meters and it's about 1 in 3.4: NASA lists 11,343 of those.

Against a random player; a tie counts as not winning.
1 in 243 tries 0.41%
Each game you win 1 time in 3, so five in a row is 3 × 3 × 3 × 3 × 3.
Fun fact: Ten wins in a row would be 1 in 59,049: 14 times rarer than being dealt four of a kind in poker.

Any two people, compared letter by letter.
1 in 1,000 DNA letters 0.1%
The US National Human Genome Research Institute says all humans are 99.9% identical in their genetic makeup, so about 1 letter in 1,000 differs.
Fun fact: Pick a random spot in your genome: rolling snake eyes (1 in 36) is about 28 times easier than landing on a difference.
