    4/7.

    Step-by-step explanation:

    This the question in which marbles have to be taken out of a bag. Odds in another word for probability.

    Total number of marbles in the bag = 2 Blue + 1 Green + 4 Red = 7 marbles.

    Required marbles = 3 red marbles.

    Therefore:

    P (a red marble is selected in the first attempt) = Red Marbles / Total Marbles.

    P (a red marble is selected in the first attempt) = 4/7.

    Therefore, the correct answer is 4/7!
