    Step-by-step explanation:

    P (a green grape and a seedless tangerine)

    =P (green grape) x P (seedless tangerine)

    The bowl of grapes has 9 green grapes and 16 red grapes.

    P (green grape) = green grapes / total grapes

    =9 / (9+16)

    =9/25

    The bowl of tangerines has 7 seeded and 3 seedless tangerines.

    P (seedless tangerine) = seedless / total

    =3 / (3+7)

    =3/10

    P (a green grape and a seedless tangerine)

    =9/25 x 3/10

    =27/250

    Step-by-step explanation:

    There are two requirements: a green grape and a seedless tangerine

    For grapes, total number of grapes is 9+16 = 25 and 9 are green

    Prob (green grape) = 9/25

    For tangerines, total number of tangerines is 7+3 = 10 and 3 are seedless

    Prob (seedless tangerine) = 3/10

    Prob (a green grape and a seedless tangerine) = 9/25*3/10

    =27/250
