Im assuming 2222 could be used. I posted the question exactly how it was asked me.

It does not seem to be so much of a statistics question. If 4 digits are to be present and reuse of a digit is allowed each thousand starting with 2, 4, 6, and 8 meet the requirement. That makes it 4000.

that depends, is it allowed to reuse the digits ?
