Question 1194017: Ivy and Romer took a mechanical pre-board exam conducted by College of

A very poorly presented problem; more information is needed:
Are the 20 questions true/false? or multiple choice with 4 answer choices? or 5 answer choices?
Also, the wording of the problem uses bad English. The "probability that they both have 5 correct answers" could mean the EACH of them has 5 correct answers, or it could mean that the two of them TOGETHER have a total of 5 correct answers.
