162 = never use a credit card
1223 = use credit card sometimes
2831 = use a credit card frequently
Probability that a randomly selected person uses a credit card frequently:
1223 / 162 + 1223 + 2831
1223 / 4216
As a percentage, this is about a 29 percent chance. I guess you could say it's unlikely, because the probability is only 29 percent.
