Mac or PC? A recent census at a major university revealed that 60% of its students mainly used Macs. The rest mainly used PCs. At the time of the census, 67% of the school's students were undergraduates. The rest were graduate students. In the census, 23% of respondents were graduate students who said that they used Macs as their main computers. Suppose we select a student at random from among those who were part of the census. What's the probability that this person is a graduate student or mainly uses a Mac?
