I've been sitting and writing this code for about 4 hours and I still can't get it work
can someone help me please?
this is the html code:

<!DOCTYPE html>
<html>
<head>
  <link rel='stylesheet' type='text/css' href='style.css'>
</head>
<body>
<button id = "button">test</button>
<h1 style = "font-size: 1.5em; font-family: verdana; color: black;">the answer</h1>
<script src='https://code.jquery.com/jquery-3.1.0.min.js'></script>
<script type="text/javascript">
$('#button').on('click', function() {
	var randomAnswer = Math.random();
	if(randomAnswer < 0.1) {
alert("hey");
	} else if(randomAnswer <= 0.2) {
alert("hey");
	} else if(randomAnswer <= 0.3) {
alert("hey");
	} else if(randomAnswer <= 0.4) {
alert("hey");
	} else if(randomAnswer <= 0.5) {
alert("hey");
	} else if(randomAnswer <= 0.6) {
alert("hey");
	} else if(randomAnswer <= 0.7) {
alert("hey");
	} else if(randomAnswer <= 0.8) {
alert("hey");
	} else if(randomAnswer <= 0.9) {
alert("hey");
	} else {
alert("hey");
	}
});
$(document).ready(main);
</script>
</body>
</html>

I added the alert("hey"); just to see if it works and I don't know why but the jquery doesn't interact with the html.

What I have tried:

I went to a lot of guides and tutorial and to w3schools and still didn't find how to fix it

It boils down to the very basic of jQuery, the Selectors. Do you understand the relation between:

<button id = "button">

and

$('#button')

? If not, head over to jQuery Selectors[^]. Once you learn how the jQuery selector work, apply it to your code. Let say you want the answer to be displayed in the h1 tag,

HTML

<button id = "button">test</button>
<h1 id="answer">the answer</h1>
<script src='https://code.jquery.com/jquery-3.1.0.min.js'></script>
<script>
$('#button').on('click', function() {
    var $answer = $("#answer");
	var randomAnswer = Math.random();
    $answer.text(randomAnswer);
});
</script>
