Marissa is drawing erasers from a bag containing $6$ pink erasers, $2$ yellow erasers, $5$ green erasers, and $3$ purple erasers.

1. What is the probability that she will draw a pink eraser?

   Hint (a):

   $\frac{\text{number of pink erasers}}{\text{total number of erasers}}$

   Answer (a):

   $\frac{6}{16}$

2. If one yellow, two green, and one purple eraser are added to the bag, what is the new probability that she will draw a pink eraser?

   Hint (b):

   What is the new total number of erasers?
   Does the number of pink erasers change?

3. In which situation is it more likely that she will draw a pink eraser?

   Hint (c):

   Compare the probabilities in each situation.
   Which probability is higher?

   Answer (c):

   It is more likely for Marissa to draw a pink eraser in the first situation
   because

   $\frac{6}{16} > \frac{6}{20}$
