  • Question
  • Out of sixty students, there are 14 who are taking Economics and 29 who are taking Calculus. What is the probability that a randomly chosen student from this group is taking only the Calculus class ?


  • Options
  • A. 8/15
  • B. 7/15
  • C. 1/15
  • D. 4/15

  • Correct Answer
  • 7/15 

    Explanation

    Given total students in the class = 60
    Students who are taking Economics = 24 and
    Students who are taking Calculus = 32
    Students who are taking both subjects = 60-(24 + 32) = 60 - 56 = 4
    Students who are taking calculus only = 32 - 4 = 28
    probability that a randomly chosen student from this group is taking only the Calculus class = 28/60 = 7/15.
