Edit: Original supposition on the problem completely wrong. The cause of you getting all zeros is that the state is not seeded. You need to fill state with something ‘random’. This code work. Note that the function seed() is in absolutely no way scientifically proven to be good – in fact, I just made it … Read more
Use a for loop: for num in range(5): # Replace “print” below, with the code you want to repeat. print(num) To repeat all questions, excluding “whats your name..” include the part of the code you need in the loop: import random name=input(“What is your name?”) print (“Alright”,name,”Welcome to your maths quiz”) score=0 for question_num in … Read more
You shall direct print it. import java.util.Random; public class compountInterest { public static void main(String[] args){ System.out.println(“” + new Random().nextInt(6)); System.out.println(new Random().nextInt(6)); //Appending empty char at start makes no difference } } 6 solved Why do I need a temporary variable to store the value of a Random method? [closed]
I am not really sure that I got all of your requirements but this might be the script you are searching for: N = 10; % count of numbers p = 0.2; % switching probability a = 5; b = 20; % init empty numbers and get the first random number numbers = zeros(N,1); numbers(1) … Read more
You can do: diceroll1() + diceroll2() since the compiler sees it as value that diceroll1() returns + value of diceroll2(); 0 solved How can I use the output of a rand function, simulating 2 die rolls?
Read the file sequentially – thats the easiest route. Then randomly shuffle the collection. Actually, another question. Could you use math.random() to look at the lines of the text file and if, lets say, the line 5 comes up then you remove it from the parameters you set for math.random()? It would pick from 0-9 … Read more
Just a note, the first commenter is correct, you probably could have found this through a bit of Googling, but here’s the answer as best as I can explain it: Let’s take that code: Random random = new Random(); The first random just says what type of data the variable is going to store – … Read more
Use a total variable and add the generated number to the total import random x = 0 total = 0 while x<10: number = random.randrange(1,10) print(number) total += number x=x+1 print(total) 0 solved i’ve generated random numbers. Now i want to add all the numbers that are generated. What is the code to add them … Read more
#include <cstdlib> … if(rand()%2)a++; else a–; That’s not very hard to do. Its simple trick. 0 solved Radomly add or subract 1; [closed]
<html> <body> <script> Array.prototype.randomElement = function () { return this[Math.floor(Math.random() * this.length)] } var list1 = [ “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”]; var list2 = [ “a”, “b”, “c”, “d”, “e”, “f”, “g”, “h”, “i”]; var list3 = [ “car”, “horse”, “gym”, “fair”, “boat”]; function myFunction() { document.getElementById(“demo”).innerHTML = list1.randomElement() + … Read more
The Birthday Paradox predicts that the probability of duplicates in random numbers is much higher than you’d think. For example, it predicts that, with a mere 23 random people, there’s a greater than 50% chance of two of them have the same birthday. By the Pigeonhole Principle, it takes 367 people for there to be … Read more
random.shuffle is your friend, according to the docs random.shuffle(x[, random]) . Shuffle the sequence x in place. import random #Convert string to list of chars li = list(‘ABDEB’) for i in range(5): #Shuffle the list, the last shuffled list is shuffled every time random.shuffle(li) #Convert list to string again and print print(”.join(li)) Output might look … Read more
As you only return h, you don’t actually need t. It is also not needed to use randrange — you can achieve the same with random. For the actual counting you can use sum, and the boolean result can be converted to 0 or 1 with int: def prob(times): return sum(int(rd.random() < 0.7) for _ … Read more
If you wanted to be clever, you could make sure the least significant bit of the number is not set: int num = (new Random().nextInt(199) & ~1) + 2; This will ensure that the number is always even. Thanks Eyal Shneider and Omaha Marcelo‘s comment from the OP is the correct answer, though. Get a … Read more
When you use class instead of id then you can do something like this. Get all the hello elements Create a random Index in the range from zero to the length of your elements Set the style.color of this random Index element in your helloElements to red let helloElements = document.querySelectorAll(“.hello”); let ind = (Math.floor(Math.random() … Read more
