    A. P = 1.7% (rounding to the next tenth)

    B. P = 33.3% (rounding to the next tenth)

    Step-by-step explanation:

    1. Let's review the information given to us to answer the question correctly:

    Number of red cards = 20

    Number of blue cards = 20

    Number of green cards = 20

    Total number of cards = 60

    2. A. What is the probability that a randomly selected card will be Green 1?

    Let's recall that the formula of the probability is:

    P = Number of favorable outcomes/Total number of possible outcomes

    Replacing with the value we have:

    P = 1/60 = 0.017

    P = 1.7% (rounding to the next tenth)

    B. What is the probability that a randomly selected card will be red?

    P = Number of favorable outcomes/Total number of possible outcomes

    Replacing with the value we have:

    P = 20/60 = 0.333

    P = 33.3% (rounding to the next tenth)
