A teacher decides to play a game to collect homework. Each day, when students walk into class, they select a token from a bag that contains red and gold tokens. If the token selected is gold, the student will not have to turn in their homework; however, if the token selected is red, they must turn in their homework. The teacher tells the class that there is a 30% chance of selecting a gold token. The students pull a token all five school days in one week. Which of the following correctly represents the probability that a student will not have to turn in homework exactly two times?
a. 0.09
b. 0.343
c. (0.33)^3 (0.7)^2
d. 5/2 (0.3)^2(0.7)^3
e. 5/2 (0.3)^3(0.7)^2
