C :

#include <stdio.h>
 
int main()
{
    int a;
    float b1,b;
    while(scanf("%d",&a) != EOF)
 {
 if (a==1)
  {
  b1=0.7*0.7*0.7*0.7*0.7*0.7+6*0.7*0.7*0.7*0.7*0.7*0.3
   +15*0.7*0.7*0.7*0.7*0.3*0.3; 
   b=1-b1;	
  } 
   
 else
   b =0.0001;
     printf("%.4f\n",b);	
  
  }
    return 0;
}

C++ :

#include <string>
int main() 
{ 

    int a; 

 

    while(scanf("%d",&a) != EOF) 

 {if (a==1){
 	
printf("%.4f\n",0.2557);}
	     
 

else  {
	printf("%.4f\n",0.0001);
}
 
}
}

Pascal :

program y1;
 var
  a:integer;
 begin
  readln(a);
  if a<>0 then
  writeln('0.2557')
  else writeln('0.0001');
 end.

Java :

import java.util.Scanner;

public class Main{

	public static void main(String[] args) {
		Scanner reader = new Scanner(System.in); 
		int a;
		while(reader.hasNext()){
			a = reader.nextInt();
			if(a==0){
				System.out.println("0.0001");
			}
			else if(a==1){
				System.out.println("0.2557");
			}
		}

	}
