A collection of 100 computer programs was examined for "syntax", "input/output" and "other" errors other than the above. Of these 100 programs, 20 had "syntax" errors, 10 had "in/out" errors and 5 had "other" errors, 6 had "syntax" and "in/out" errors, 3 had "syntax" and "other", 3 had "in/out" and "other" errors, and 2 had all three types of errors considered. A program is randomly selected from this collection. Find the probability that the selected program has exclusively "syntax" errors.
