Answer / iman.k.sarkar
if i know one door with the beast then the probability of
getting the beauty increases from 33% to 50%. now since the
question asks about the maximum chance hence by swapping the
door(from the initial choice) the chance increases from 50%
to 66% and the probability of getting the beast is 33%.
