Does a coin land on heads more often?
They found that a coin has a 51 percent chance of landing on the side it started from. So, if heads is up to start with, there’s a slightly bigger chance that a coin will land heads rather than tails. When it comes down to it, the odds aren’t very different from 50-50.
Can you have probability of 0?
