6. Some teachers argue that they don't like multiple choice tests because a student can just guess at all the answers and still pass the test. If a teacher gives a multiple choice test with 20 questions, with each question having 4 possible answers (a,b,c,d) then what is the probability that a student who is randomly guessing will get a 70% or better on the test? (Do not round) Does this support the claim that a student could just guess and pass the test?
