Say there are two roullette wheels. Wheel A has been spun 20 times and has come up red every time! Oddly enough, Wheel B has alternated red and black outcomes for it's 20 spins, and the 20th spin was black. Which wheel is more likely to hit black on it's 21st spin?

Look, I'm not saying you can definitely know which wheel is going to hit which, I'm not that dense, and thats why they call it gambling. However, the wheel that hit red 20 times in a row is a little more likely to hit black than the one that has been behaving properly according to probability.

actually, since roullette wheels are mechanical devices, when it lands on red super often it is most likely that there is an inbalance or groove causing it. so it would be more likely to hit on red in the future.
