    Answer:

    94

    Step-by-step explanation:

    Let the universal set be U. n(U) = 243

    let the right handed high school students in their junior year be R. n(R) = 139

    Complement of the given event refers to the left-handed people. Therefore, number of outcomes in the complement of right handed people, n(R’) = n(U) – n(R) = 243 – 139 = 94. Hence, the required answer is 94.
