    Possibility that the students selected are both girls = 31.25%

    Step-by-step explanation:

    It is given that

    A science class have 5 girls and 3 boys in 7th grade

    And 2 girls and 2 boys in the 8th grade

    In 7th grade total students = 8

    In 8th grade total students = 4

    Total possibilities = 8 x 4 = 32

    The teacher randomly selects a 7th grade and an 8th grade

    The number ways a girl selected from 7th grade = 5c1 = 5

    The number ways a girl selected from 8th grade = 2c1 = 2

    Total possibilities = 5 x 2 = 10

    Probability that the students selected are both girls = 10 / 32 = 31.25%
