#include <iostream>
using namespace std;

double calculate_odd_average(int array[], int size) {
int sum=0;
int count=1;
for(int i=0; i<size; i++) {
if(array[i]%2==1) {
sum+=array[i];
count++;
}
}
return (double)sum/count;
}

double calculate_even_average(int array[], int size) {
int sum=0;
int count=1;
for(int i=0; i<size; i++) {
if(array[i]%2==0) {
sum+=array[i];
count++;
}
}
return (double)sum/count;
}

double calculate_all_average(int array[], int size) {
int sum=0;
for(int i=0; i<size; i++) {
sum+=array[i];
}
return (double)sum/size;
}

int main() {
int array[20];
for(int i=0; i<20; i++) {
cin>>array[i];
}
cout<<"Odd average: " << calculate_odd_average(array,20)<<endl;
cout<<"Even average: " << calculate_even_average(array,20)<<endl;
cout<<"All average: " << calculate_all_average(array,20)<<endl;
return 0;
