Question

A student took a 25 question true and false test answering the question randomly without reading. If a score of 18 is correct is the minimum passing graade, how likely is it that the random guesser will pass the test?

This is binomial although there is a slight twist in the Q

Answer 1

You can use a binomial probability table to determine the probability. Find P(18) through P(25), then add all the probabilities together for a total.
