Question 1171674

Private vehicle	     636	908	590	257	256	2647
Public transportation	9	54	96	62	108	329
Other means.          	115	70	23	7	7	222
Total                	760      1032  709	326	371	3198

Public transportation has 329 (end of the 2nd row)
60 or more minutes is 371 (fourth column total)
That is 600
subtract where they intersect (double counting) which is 108.
There were 492 of 3198 (15.4%)

Given they used public transportation (329), number that they had commute of 60 or more min was 108. That probability is 32.8%.
