in a multiple choice test the probability of getting the correct answer by guessing alone is 20%. what are the odds against getting the correct answer by pure guessing?
-------------
Formula: Odds against = P(against)/P(for)
Your Problem:
P(correct) = 0.2
P(incorrect) = 0.8
-------
Odds against = 0.8/0.2 = 4:1
