Chances

random.js

//random number between 1 and 6:
dice = Math.floor((Math.random() * 6) + 1);
alert(dice);

float.js

maxTime = 20.00; //20 seconds
minTime = 5.00; //5 seconds

actualTime = Math.random() * (maxTime - minTime) + minTime;
alert(actualTime.toFixed(2));

//^^ .toFixed(2) rounds to decimal places!

games.js

//random number between 1 and 3:
computerGuess = Math.floor((Math.random() * 3) + 1);
computerHand = "";
switch(computerGuess){
    case 1:
        computerHand = "PAPER";
        break;
    case 2:
        computerHand = "ROCK";
        break;
    case 3:
        computerHand = "SCISSORS";
        break;
}
alert("Computer chose: " + computerHand);

1. Generate a random number between 1 and 52.
   


2. Generate a random decimal number between 0 and 100.
   


3. Can you add a second dice to the dice roll game, and tally the two dice? So that you could use this script in a game of Monopoly.
   


4. Generate a random number between 1 and 3, and this time, spell out the random number (depending on what it is), e.g. "One", "Two", or "Three".
   


5. Can you add input to the Paper Rock Scissors game, so that I can play against (and challenge) the computer?
   


6. Can you make a maths game, that generates a random sum that I have to answer (e.g. 4 + 5, 6 - 3, etc.) When I answer the sum, it should say correct or incorrect. The whole program should be random (including the operation - multiplication, subtraction, addition etc.) To make the program very difficult, see if you can work out how to exclude negative answers, so that if I am asked a subtraction problem, the result isn't a negative number.
