    Answer:

    Total number of students = 45

    total number of boys = 25

    thus total number of girls = 45 – 25 = 20

    P(E) = \frac{possible number of outcomes}{total number of outcomes}

    P(E) = \frac{20}{45}

    P(E) = \frac{4}{9}

    thus the probability of a girl is  \frac{4}{9}

    Answer:

    Total people=45

    Boys=25

    Girls=45-25

           =20

    Probability of a girl=20/45

                        =4/9
