To demonstrate probabilities, a mathematics teacher had students draw marbles from a bag which contained 9 yellow marbles and 8 blue marbles. During class, the bag was dropped and 2 yellow marbles and 2 blue marbles were lost. Tell whether the loss of marbles changes the probability of drawing a blue marble from the bag. If so, was the probability increase or decreased? Support your answer by calculating the probability for each situation

The loss of marbles did not change the probability.

Step-by-step explanation:

This is because the loss was even you lost 2 marbles from both category which keeps them equal similar to when you set two equations equal to one another and then you subtract 2 from each side the sides are still equal.
