    Let the probability of yellow balls be x.

    Total balls=36

    Probability (White Balls)=2/9

    Therefore,2/9+x=1

    By calculating,

    The value of x=7/9

    Let number of yellow balls be y.

    7/9=y/36

    By evaluating,

    We get y=28.

    Hence,The number of yellow ball is 28

    I HOPE THIS HELPS.
