    What is combination?
    A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.
    Given:
    Number of boys =17
    Number of girls =18
    Total number of students= 35
    Now,
    total number of combinations= 35 C 10
    =183579397
    Now,
    Number of combination that one girls from 18 girls = 18C1
    =18
    and
    9 boys from 17 = 17C9
    =24310
    Hence, total number of  ways can be selected = 183579397
