A college food court surveyed 683 students to see how many drink soda, how many drink tea, and how many drink coffee.
The Venn diagram below shows the results. (Each number gives the number of students who fall into that Venn diagram category.)

(a) How many of the students drink exactly two of the three drinks?
(b) How many of the students don’t drink tea?
(c) How many of the students drink neither coffee nor soda, but do drink tea?
