My question is: There are 32 students in a statistics course. 25 percent of the class received an A. 1/4 of the remaining students got either a B or C, and the rest of the students failed. How many students failed? Your thoughts:

A grade:32(.25) = 8. 32 - 8 = 24 students remaining. B / C grade:24 / 4 = 6. 24 - 6 = 18 students fail. The final answer: 18.
