Answer 1

 return `rgb(${Math.random()*256<<0}, ${Math.random()*256<<0}, ${Math.random()*256<<0})`;
}

Answer 3

function t7() {
  let x = Math.floor(Math.random() * (255 - 0 + 1)) + 0;
  let y = Math.floor(Math.random() * (255 - 0 + 1)) + 0;
  let z = Math.floor(Math.random() * (255 - 0 + 1)) + 0;
  return `rgb(${x}, ${y}, ${z})`;
}

Answer 4

Decision:

function t6(a, b) {
    return Math.floor(Math.random() * (a - b + 1)) + b
}

function t7() {
    return `rgb(${t6(0, 255)}, ${t6(0, 255)}, ${t6(0, 255)})`
}
    document.querySelector('.button').onclick = function () {
    document.querySelector('.out').style.background = t7();
}​
