For all potential students, if the population chance of dropping has not changed from 2011 to 2015, how many students would have your expected to drop in 2015? Rounding to whole numbers your answer is: a. 250 b. 258 c. 582 d. none of the other answers are correct

Expected drop in 2015 = 850*43.75% = 371.875 ~ 372
