To demonstrate probabilities, a mathematics teacher had students draw marbles from a bag which contained 6 yellow marbles and 10 blue marbles. during class, the bag was dropped and 2 yellow marbles and 3 blue marbles were lost. explain whether the loss of marbles changes the probability of drawing a blue marble from the bag. be sure to state whether the probability of choosing a blue marble stays the same, increase or decreases once the marbles were lost? explain why you believe this.
