11-40.

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?

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

$\frac{6}{16}$

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?

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?

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

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

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