There are 4 green marbles, 5 blue marbles, 4 red marbles, 3 orange marbles, and 1 pink marble in a bag. Jose, Juan, and Mark are each going to choose one marble in that order. After they choose their marble, they do not put it back in the bag. Jose chooses a red marble. Juan chooses a pink marble. What is the probability that Mark chooses a green marble? (give your answer as a decimal or percent)
0.20 or 20% After Jose and Juan choose their marbles, there are only 15 marbles left. Since Juan chose a red marble, there are only 3 red marbles left. When Mark chooses a marble, there are 3 red ones out of 15 total. 3/15 = 1/5, or 0.20.
