    8/13

    Step-by-step explanation:

    Step 1 : Write all the data

    Total number of students = 26

    Number of girls in class = 10

    Number of boys in class = 26-10 = 16

    Step 2 : Find the probability

    Probability of pulling out a boy's name = number of boys in class

    Total number of students in class

    = 16/26

    Simplify:

    16/26 = 8/13
