[R] Question

I have a problem that I am trying to solve and I am not sure how to do it in R.

Suppose, that 16 numbers are choosen at random from 0 to 9, what's the probability that their average will be between 4 and 6. I typed the following code:

sample(0:9, 16, replace =TRUE)

    [1] 3 2 5 0 4 4 8 3 5 1 6 8 2 3 7 6

Is what I got, however I realize the set.seed function locks in the number I get every time.
My question is in order to run a true random sample, wouldn't I have to use the runif function? And then deliminate the sample to show the numbers that lie between 4 and 6? If that's the case, how do I do that?
