How to shuffle a list in apex salesforce - salesforce

Question

I want to shuffle a list record , I am create a VF page to show the Question on that. when page is reload then every time want Another Question on the page randomly.
I am using
Integer count = [SELECT COUNT() FROM Question__c ];
Integer rand = Math.floor(Math.random() * count).intValue();
List<Question__c > randomQuestion = [SELECT Id, Question__c
FROM Question__c
LIMIT 1000 OFFSET :rand];
system.debug('<<<<<<<<<>>>>>>>>>'+randomQuestion);
in developer console its going good but on vf page its not working
Question not showing or limited Question showing
Any one suggest me better way to show the Question on the vf page
Thanks In Advance

I built a solution that users the Fishe-Yates shuffle:
list<Question__c> quesLst = [select id, Question__c, RecordType.Name, Answer__c, Option_A__c, Option_B__c, Option_C__c, Option_D__c from
Question__c limit 1000];
randomize(quesLst);
private list<Question__c> randomize(list<Question__c> lst){
integer currentIndex = lst.size();
Question__c Question;
integer randomIndex;
// While there remain elements to shuffle...
while (0 != currentIndex) {
// Pick a remaining element...
randomIndex = integer.valueOf(Math.floor(Math.random() * currentIndex));
currentIndex -= 1;
// And swap it with the current element.
Question = lst[currentIndex];
lst[currentIndex] = lst[randomIndex];
lst[randomIndex] = Question;
}
return lst;
}
