Generating random numbers, while excluding some numbers

Question

I want to generate random numbers between 1 and 13 (including 1 and 13), while excluding numbers 6 and 9
Please tell me theres an easy fix to this issue --

Answer 1

lemme know if it compiles
import java.util.*;
public class RandomNumber {
public static void main( String[] args) {
int numWins = 0;
for( int i = 1; i < 101; i++) {
boolean x = true, y = true;
int number = 0;
while(!x && !y && number != 6 && number != 9)
number = 1 + (int) (Math.random() % 13);
x = number >= 1;
y = number <= 13;
int number2 = 0;
while(!x && !y && number2 != 6 && number2 != 9)
number2 = 1 + (int) (Math.random() % 13);
x = number2 >= 1;
y = number2 <= 13;
int number3 = 0;
while(!x && !y && number3 != 6 && number3 != 9)
number3 = 1 + (int) (Math.random() % 13);
x = number3 >= 1;
y = number3 <= 13;
int number4 = 0;
while(!x && !y && number4 != 6 && number4 != 9)
number4 = 1 + (int) (Math.random() % 13);
x = number4 >= 1;
y = number4 <= 13;
int DrawAgain = 2;
if (number == DrawAgain) {
System.out.println( "A Random number between 1 and 10: " + number);
System.out.println( "A second Random number between 1 and 10: " + number2);
if (number2 == 8) {
System.out.println( " Piece made it home successfully");
numWins++;
if (number2 == DrawAgain) {
System.out.println( "A third Random number between 1 and 10: " + number3);
if (number2 == 7) {
System.out.println( " Piece made it home successfully");
numWins++;
if (number3 == DrawAgain) {
if (number4 == 7)
System.out.println( " Piece made it home successfully");
numWins++;
else {
System.out.println( "A Random number between 1 and 10: " + number);
if (number == 10) {
System.out.println( " Piece made it home successfully");
numWins++;
System.out.println(" Number of times piece made it home successfully " + numWins);
}
