#include <iostream>
using namespace std;
int main() {
int N, K;
cin >> N >> K;
int total = 0;
for (int i = 0; i < K; i++) {
int r;
cin >> r;
total += r;
}
double min_rating = (double) (total - 3 * (N-K)) / N;
double max_rating = (double) (total + 3 * (N-K)) / N;
cout << min_rating << endl;
cout << max_rating << endl;
return 0;
}
