    The probability can be written as;

    6/18

    0.333

    33.3%

    Step-by-step explanation:

    First we find the total number of marbles.

    4 + 5 + 6 + 3 = 18

    Now write the probability in the form of (favourable outcomes / possible outcomes), or 6/18.

    Now let's divide.

    6 : 18 = 0.33333333 ... repeating decimal

    0.333 * 100 = 33.33333 ... %

    We can also round this to 33%
