Question
A coin toss is usually fair – when a coin is tossed, it has a 50% chance of landing on heads, and a 50% chance of landing on tails. In this problem, you will design an unfair coin using the Random class and implement it as a method.
Utilize an instance of the random class, Random r = new Random(), to design an unfair coin.
Write a valid Java method (including a method header) that takes no arguments and returns the string “heads” 60% of the time and returns the string “tails” 40% of the time. Your code may use any valid methods in the Random class
Explanation / Answer
Hi, Please find my implementation.
Please let me know in case of any issue.
import java.util.Random;
public class UnfairCoin {
/*
* This method return head ot tail with probability of 60:40
*/
public static String toss(){
Random random = new Random();
int rand = random.nextInt(5); //0,1,2,3,4 ( 5value)
if(rand <=2)
return "head"; // returning head for three value out of 5: 0, 1,2
else
return "tail"; // returning tail for 2 value out of 5 : 3,4
}
public static void main(String[] args) {
System.out.println("Toss: "+toss());
}
}
