We need to find the probability of a team having a winning season given that their attendance is more than 3.0 million. Out of the 30 teams, we know that only 5 teams (as per the given data) had attendance of more than 3.0 million. Therefore, we need to find the number of teams that had both attendance of more than 3.0 million and a winning season. According to the data, there were 4 teams with such attendance and winning season. Therefore, the probability is 4/5. Hence, the correct answer is option D.
