    so the probability of getting a white marble is \(\dfrac{5}{12}\)

    when you take the white marble out and don't replace it, the total changes to 11

    now to find out the probability of pulling out a white marble and then a blue marble is \(\dfrac{5}{12}*\dfrac{4}{11}\) @cadeneveah11 multiply that for me
