11-40.
1. Marissa is drawing erasers from a bag containing 6 pink erasers, 2 yellow erasers, 5 green erasers, and 3 purple erasers. Homework Help ✎

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

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?

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

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

$\frac{6}{16}$

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

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

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