Question 1194017: Ivy and Romer took a mechanical pre-board exam conducted by College of
Engineering and Architecture of BISU. Assume that the exam has 20 items and the two
of them are not very well prepared for the test and they answer the questions randomly.
Find the probability that they both have 5 correct answers. Answer by greenestamps(13206) (Show Source):
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.
