A sample of 820 adults showed that 88 of them had no credit cards, 118 had one card each, 51 had two cards each, 81 had three cards each, 65 had four cards each, and 417 had five or more cards each. Suppose one adult is randomly selected from these 820 adults. Find the probability that this adult has exactly three credit cards. P(A) = # of outcomes favorable to A/ # number of outcomes for the experiment
