A bag with 12 marbles has 3 blue marbles and 9 yellow marbles. A marble is chosen from the bag at random. What is the probability that it is red?
p(red) = 0/12 = 0
Since there are no red marbles in the bag, the probability of choosing a red marble is 0.
To find the probability of selecting a red marble, we need to determine the total number of red marbles in the bag. However, the information given states that the bag contains only blue and yellow marbles, so there are no red marbles in the bag.
Therefore, the probability of selecting a red marble from the bag is 0.
