    The "population" consists of 72 students, 9 of whom plan to take "dance" and 63 of whom plan to take other electives.

    Thus, the experimental probability that a given student from this group of 72 will take dance is 9/72. Reduce this fraction to lowest terms.

    Total amount of students=72

    p (dance) = 9/72

    divide both numerator and denominator with 9

    1/8

    The experimental probability is 1/8
