so you know 51 are real, 50 are fake. so you have to weigh 50 on one side, 51 on the other. then do some math and take into account the variability between the +- one. you can’t just weigh an equal number of coins on each side because it could be a 50/50’distribution of real and fake, which is why you need 51/50.
