in a single session of playing until either it lands black seven times in a row or lands on zero twice in a row.
what is the probability of which will happen first?

Surely 7 x blacks ftw?
2 x zero = 37x37 innit?

Oh wait that's all wrong...... It depends how many spins of the wheel there are. Zero is only 36-1 once a zero has already spun

(18/37)^7 > (1/37)^2
(18/37)^7 / (1/37)^2 = 8.8x more likely to see 7 reds in a row

Or if you start after seeing the first one.
1/37 > (18/37)^6
1/37)^2 / (18/37)^6 = 2

same number twice in a row is 1/1444

same colour 8 times in a row is 169/1 (based on a dbl zero wheel)
