To find the probability of a faculty member opposing the change to a quarter system, we need to look at the column for "Oppose" and add up the total number of faculty members who oppose the change (which is 20) and then divide by the total number of faculty members (which is 50). This gives us a probability of 20/50, which simplifies to 2/5 or 0.40, so the correct choice is C.
