Plotting percentages. Of the students in your dorm, 30% are business majors, 15% are engineers, 20% are science majors, 10% are humanities majors, and the rest are social science majors. (There are no double majors.) If there are 600 students in your dorm, how many are social science majors? If you choose a student at random, what’s the probability that they are a
Science or engineering major? Make a bar graph similar to those in this section to show the probabilities for each type of major.
