    The chances you will get a red marble over a white or blue marble is 30%

    Step-by-step explanation:

    If you add 5 + 3 + 2 you will get 10

    You then turn it into a fraction

    3/10 is the chance you will get a red over a blue or white, now we need to convert it into a percentage by turning to 10 into 100 and multiplying 3 x 10

    Once you have done that you should have 30/100

    Take the 100 away and turn it into a percentage

    The answer would be 30%
