Question

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

​

Answer 1

The loss of marbles did not change the probability.

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.
