Pixel for Facebook

We are hosting an event that I want to promote on Facebook with a tracking pixel. How do I install the pixel code to our website? Here is the "code":
<!-- Facebook Pixel Code -->
<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
' connect.facebook.net/en_US/fbevents.js ');
fbq('init', '745882232530581');
fbq('track', 'PageView');
</script>
<noscript><img height="1" width="1" style="display:none"
src=" www.facebook.com/tr?id=745882232530581&ev=PageView&noscript=1 "
/></noscript>
<!-- End Facebook Pixel Code -->

We do not support 3rd party scripts, if you want to put this on your site you do so on your own and if it causes issues we will not debug and can only offer to clear the page,
