    Step-by-step explanation:

    Probability is a way of expressing the chances of an outcome in math.

    In this problem, there is a 30% (30 percent) chance of choosing a red marble out of 40 marbles

    We can convert 30% to a decimal by dividing it by 100

    30 - >.3

    We can then multiply that decimal by the total amount of marbles

    .3 * 40

    12 marbles should be red.
