    Answer:

    \frac{7}{31} = 0.2258 = 22.58\% probability that a randomly selected student prefers hip hop music.

    Step-by-step explanation:

    A probability is the number of desired outcomes divided by the number of total outcomes.

    In this question, we have that:

    14 students prefer hip hop music

    There are 18 + 8 + 20 + 14 = 62 students

    So

    p = \frac{14}{62} = \frac{7}{31}

    \frac{7}{31} = 0.2258 = 22.58\% probability that a randomly selected student prefers hip hop music.
