A survey of 1000 students found that 41% of the surveyed students were freshmen, 31% were juniors, and 67% lived on the college campus. (A) If 260 of the surveyed students were freshmen living on the college cam- pus, then how many surveyed students were either freshmen or living on campus? (B) Suppose from a previous survey you know that of interviewed juniors, only 23% live on campus. What is the probability a surveyed student is a junior or someone that lives on campus?
