Now before we carry out event number two, we don't know what the outcome is. So it can be tails or it can be heads. Moreover, the outcome of event number one has absolutely no influence. It does not actually affect the outcome of event number two. And that's exactly what we mean by two events being independent of one another. So two events are said to be independent of one another if the currents of one of the events does not actually influence or affect the occurrence of the second event.
