The bag contained 6 red marbles and 10 blue marbles. Bill removed a red marble. He then replaced it. What is the probability Bill will remove a blue marble on his next try?
its just the chance of drawing a blue marble. the drawing of the red marble was independent to the current drawing of the blue marble, so the probability of drawing a blue marble is just the number of blue marbles over the total number of marbles. that is 10/16 or 5/8
