MathRevolution question does not specify whether digits can be repeated or not ; seems answer is co relating to the latter...
since we have 4 digits
and >3000 so
first digit can be either 3,5,7 only '3' possibilities ;
second digit : 3 possibliites ; could be any of
third digit 2 option and 4th option 1

so 3*3*2*1 = 18 IMO E

=>

We need to count the \(4\)-digit numbers with thousands digits \(3, 5\) and \(7\).
The number of \(4\)-digit numbers beginning with \(3\) is \(6\).
The number of \(4\)-digit numbers beginning with \(5\) is \(6\).
The number of \(4\)-digit numbers beginning with \(7\) is \(6\).
Thus, the total number of such \(4\)-digit numbers is \(18 = 6 + 6 + 6.\)

Therefore, the answer is E.
Answer: E
