Roulette at Aria with the following board:

28
17
17
17
17
17
19
17
17
21
18
19
13
17

That's 8 times that 17 came up out of 14 rolls. So what are the chances of one number coming up 8 times out of 14 rolls?

1/35^8 = 4.44e-13, but that's the chances of it happening 8 times in a row. We have 14 tries, so that's where I get the dumb and can't figure out the next step.

(I have a picture of the Roulette board but can't post it until I get 20 posts. :P)

It is very likely the camera malfunctioned and registered 17 multiple times when in reality it was only one spin.

Exactly 8 times? That's C(14,8) x (1/38)^8 x (37/38)^6, which is about 1 / 1,700,000,000.
At least 8 times? That is the sum of (exactly 8 times) + (exactly 9 times) + ... + (exactly 14 times), which is about 1/1,668,600,000.

However, this wouldn't be the first time one of these displays malfunctioned.

If it did really happen, I'm sure bummed I wasn't there for it. 17 is my number on roulette (it's also my birthday.)

17 seems to be a popular favorite number in Roulette.

In this forum, I'd say it's a highly likely event to occur!
