A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,
Elan Coil [88]

Answer:

<u>720</u> possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10   (0-9 means total 10 digits)

r= 3     (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

        =10!/7!

        = 10x9x8x7!/7!

        = 10x9x8

        = 720

Nezavi [6.7K]

Answer:

The answer to this question can be given by program that  are as follows

import java.util.*;

//import package for taking input from user.

public class Main   //define class

{

public static void main (String ag[] )   //define main function

{

 int number;

 Scanner input = new Scanner(System.in);

 for (int i = 0; i < 5; i ++)                       //loo for input.

 {

  System.out.print ("Enter a number between 1 - 30:  ");

  number = input.nextInt();          //input number by the user.

 

 }

 asterisk();           //calling function.

 }

public static void asterisk()          //defination of function.

{

    //body of function.

    int n;                   //local variable.

 for (n= 0; n <= 30; n++)                  //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );                  //print value.

 }

 

  for (n= 0; n <= 30; n++)         //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );     //print value.

 }

 

  for (n= 0; n <= 30; n++)          //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );          //print value.

 }

  for (n= 0; n <= 30; n++)            //using loop for print asterisk

 

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );               //print value.

 }

 

  for (n= 0; n <= 30; n++)             //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );             //print value.

 }

}

}

Output:

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 1  

Enter a number between 1 - 30: 3

Enter a number between 1 - 30: 4

*******************************************************************************

Explanation:

In this program we take 5 time input from the user and print the value in the form of (*) that can be explain in above output section.In that program we use printf method that is also used for print the value.
