Ling is taking a quiz that consists of 3 multiple-choice questions, each having 3 answers. if she guesses on each question, what's the probability that ling will get 100% on the quiz?

There are 3 ways in which you can answer each of the question in a 3 multiple-choice question. All in all, there are 27 ways in which Ling can answer the questions. Of these combinations, only one of which will give her a 100%. Thus,
                                    probability = (1/27) x 100%
                                                     = 3.70%
Therefore, the probability that Ling will get 100% on the quiz is very lean with a value of only 3.70%. 

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
