    Answer:

    better chance without replacing first marble

    Step-by-step explanation:

    okay so we have to what ifs

    first we should find how many marbles there are total

    5+8+4+3=20

    the probability drawing a red marble first is 5/20, or 1/4 whether you replace it or not.

    if we don’t replace it,

    we now have 19 marbles, 8 of which would be blue.

    so the probability of then drawing a blue marble would be 8/19

    on the other hand, if we replace it, the probability of drawing a blue would be 8/20 or 2/5

    that is less that 8/19

    so you have a better chance of drawing a red then blue marble without replacing the first marble
