How to check if radio button is checked in jquery(javascript)

Question

Ok, so I'm using wordpress contact form 7 and I added some radiobuttons there. The code looks like this

[radio radio-681 id:radio1 "1" "2" "3"]

When I'm using dropdowns in that form they look like this

[select* three id:three include_blank class:contactForm "2" "3" "4"]

And I can call that in jquery like this

$('#three').change(function() {
    if ($("#three").val() == "3") {
        //do something
    }
});

Now my question is, how can I check if a radiobutton is checked?

EDIT: Thank you all for your fast response it works now.

$('#yourRadioButton').is(':checked')

or

$('.setOfRadioButtons:checked').val()
