You’re 100% correct.

There space 10 feasible numbers because that the very first digit, and then friend can’t use that number again, so 9 for the second, and also using the same logic, 8 for the third and 7 for the fourth. That method there’s $10 imes 9 imes 8 imes 7 = 5040$ combinations. Division this through the variety of ways to order every one, 24, and also you gain 210, together you said.

The benidormclubdeportivo.org you have done is sound, hence 210 is correct. The error have to be in creating them out, make sure you haven"t let go any.
