imagine you're trying to deactivate a bomb with a red yellow and blue wire now one of these wires is the correct option and snipping it will stop the bomb from exploding but the other two wires will cause the bomb to go off if they're snipped you choose the yellow wire but before you snip it you receive a text from the bomb's manufacturer who is watching you on a security camera he informs you that the red wire would detonate the bomb so now you must choose between yellow or blue and you might assume that it doesn't
matter because it's 50/50 but that's not actually the case in the beginning each wire had a 1/3 chance of being correct when you chose yellow the other two wires had a combined chance of 2/3 and when Red was identified as the wrong wire the odds didn't actually change they were just reflected onto the blue wire which means your chances are better if you switch to Blue
