A bag contains 10 blue, 6 green, and 4 red marbles. You choose one marble. Without putting it back, you choose a second marble. What is the probability that you first choose a green marble and then a blue marble?
first: red p: 4/20 cross multiply by x/100 that means: 20x= 400 x=20 thats the probability for red. fo the same thing for the rest. just do : numberofcolor/totalmarblescross multiplied by x/ 100 any questions? just ask me.
