Quinn loves to color, but she can be rough with her crayons. She has a box with 124 crayons, but 25% of the crayons in the box are broken. Quinn reaches in and randomly grabs 6 crayons to color with. Let C be the number of crayons selected that are broken.
e) What is the probability that all 6 crayons are in good condition?

f) What would be a good approximation for the random variable described in this scenario and what are its parameters? Why are you able to use this approximation?

g) What is the approximate probability that exactly 2 of the crayons are broken? Use the approximation you identified in part f).
