    1. what is the probability of landing on A? 2. what is the probability of landing on B? 3. what is the probability of landing on C? then, multiply all of these probabilities together to find the probability of landing on A, B, and C

    Fantastic! Now, multiply these three probabilities together: 1. probability of landing on A 2. probability of landing on B 3. probability of landing on C

    (probability of landing on A)*(probability of landing on B)*(probability of landing on C) you already found these three numbers, just multiply them together

    no, please check your math again. probability of landing on A = 1/4 probability of landing on B = 1/4 probability of landing on C = 1/4
