A statistician wants to study the number of credit cards a person has. He took a sample and found out that 89 of them had no credit cards, 129 had one card each, 84 had two cards each, 77 had three cards each, 45 had four cards each, and 401 had five or more cards each. Suppose that he randomly select one adult, what is the probability that he has more than 2 credit cards.
