Broadcasting is theprocess of putting out a lot of messages with the hope of someone responding. The outcome depends on the law of averages
The Law of Averages
The law of averages says that if you bet on enough horse races, you'll win few of them, even if you don't know anything about the horses or betting. Here's another example: If you make enough prophecies, some of them will come true. If a fortune teller will predict enough events some of them will come true. (i.e. let's say a fortune teller will predict the outcome of 100 events, the law of averages says that at least a few of them will happen. Then she can look at the few that she correctly guess about and proclaim her powers of predicting the future.)
In much the same way, if someone prays for enough different things, some of them are bound to come true. As humans, we also tend to see what we want to see. Then, if we see that some of our prayers have (seemingly) been answered (even though it is just the law of averages) it's easy to think that our prayers caused the desired thing to happen. But what about all the things that we have prayed about that never happened? It's so easy to brush them into the closet and forget about them. It's so much more builds our ego to think that our prayers made things happen.
