How random is your personal identification number or PIN? Your PIN is one of the most important safeguards for the accounts that hold your money and valuable information about you.

In some cases, up to 80% of choices come from just 100 different numbers” (Ward, 2013). Based on what you know about our ability to think randomly, explain this finding.
