"Requriement is to get count of selected checkboxes"

var count = $('input[name^="selection_checkbox"]:checked').length;

"or true"

var anyChecked = $('input[name^="selection_checkbox"]:checked').length > 0;
// OR
var anyChecked = $('input[name^="selection_checkbox"]').is(':checked');

You can use .is()

if(!$('input[name^="selection_checkbox"]').is(':checked')){
    //none of those are checked
}
