1-77.

Marissa is drawing coins from a bag that contains $5$ pennies, $4$ nickels, $5$ dimes, and $2$ quarters. .

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

Remember, probability is the number of successful outcomes out of the total number of possible outcomes.
How many nickels are in the bag?
How many total coins are in the bag?

$\frac{4}{16}= \frac{1}{4}$

2. If one penny, two dimes, and one quarter are added to the bag, what is the new probability that she will draw a nickel?

What is the new number of nickels?
What is the new total number of coins?

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