Its 1/6 to roll a 7 with two 6-sided dice. You can get weighted dice that make it more likely to land on a certain number.
Does having one weighted dice change the odds at all? My gut says no but reality is a tricky bitch and I’m convinced im wrong somehow.
Tell me the weights and I told you the probability of getting 7.
At the moment you have P(x) = {X=1 : 1/6, X=2: 1/6…X=6: 1/6). Give me the new P(X) and I calculate this for you.
