Re: Do you think God answers your payers?
lol That was the whole point and I was merely joking there just to show the argument based on ‘chance’ can be reversed to make your point invalid. 
About lottery, if one prays and wins. Yes this could be from God as well. Why not?
**God may still grant you something which he does not like.
**
God gives power to evil people, God provides means to people to brew wine, God gave free will to hman being, God let Shaitaan go loose (till end of his freedom)…etc. etc.
And yes God may not like lottery or gambling, he may grant the wish…two plausible reasons can be cited:
1- Test the person what this person would do after winning.
2- Punish the person for knowingly asking something wrong.
You must be aware of those several examples that actually winning a lottery brings misery to winners?
Simple google search will tell you.
You said Action always= equal result. Big difference. Why did you change?
You bought one ticket with small amount of money, but won the whole lottery.
Here, action does not equal the result.
You said **it can’t be both. **
How about it can be neither?
You know even a coin may not give you head or tail result.
So in that case chance is not really 50/50.
Try throwing a coin on sand. The coin may land on sand vertically.
Neither head, nor tail. 
I think recognizing the limit is being humble. You don’t think so?
Agree, the humbleness is a positive virtue. But I made a point earlier that praying to higher authority facilitates that positive virtue.
The point here is that **no one claims to be able to change God’s wish by prayer.
**
Prayer being heard means God was indifferent to the person’s need but granted the wish when asked.
If God does not want to give, no one can change his mind, no amount of prayer can do so.
Now coming to your original post and question again:
If a person feels that his or her prayer is heard by God.
**How can you prove it is not heard by God but merely a chance?
**
