Just a simple question. A weekly lottery consists of picking 6 balls, without replacement, from 49 balls numbered 1 to 49. What are the chances that the same six numbers picked in one week will be picked the following week?

My answer is that the probability is 1 in just under 14 million, that is 1 in $\displaystyle \frac{49!}{6!(49-6)!}.$ Is this correct?
