Biased wheel or random chance?
It’s a question worth asking after a roulette wheel at the Rio in Las Vegas came up Red 19 not once, not twice, but seven consecutive times late Monday night.
Poker pro Jeff Romano tweeted a picture (see below) of the roulette board, which reveals the previous 16 spins. Half of the spins were Red 19 and four of them were Black 20. The other four numbers: 0, 5, 15 and 23.
So, 12 of 16 spins (75%) on a wheel with 38 numbers landed on two numbers just one numeral apart.
If you think it’s random, consider this: The odds of the same roulette number coming up seven consecutive times on a fair wheel is 1-in-114,415,582,592.
That’s roughly one in 114 billion.
