Question 615735
every question has 6 possible answers,
                  so the probability of getting a question right = 1/6
            and      the probability of getting a question wrong = 5/6   

the probability that the student gets at least one question right will be equal to 1 minus the probability that the student gets all the questions wrong.

  so the probability 
        that the student gets at least one question right = {{{1-(5/6)^10}}} Ans
