the answer is: almost impossible. There are only 9 numbers on a European wheel that count as red, odd, and high (19, 21, 23, 25, 27, 29, 31, 33, 35), so the chance of hitting that on one spin is about 24%. To get it 7 times in a row, you’d need to multiply that chance together 7 times, which works out to roughly one in 800,000—way, way less likely than flipping 7 tails in a row with a coin. So while streaks do happen, this particular one is so rare that it’s not worth betting on or against; every spin is still totally random and independent of what happened before
