The events are not random.
Let us consider an 'event'. In this situation, a person 'x' decides to move slowly on the bike, as compared to his regular way. He reaches to a spot right at a moment when another bike suddenly comes out from a side way to the main road and is hit by a fast moving Jeep. The hitting of the bike caused the biker to fall and the stumbling bike hits the bike of 'x' and 'x' also falls down.
This event of accident is linked with the prior events on all the three individual involved. Suppose 'x' had not decided to ride slowly, he would have escaped the accident, which did not happen.
My point is, it was not possible in any way that 'x' could have escaped from the accident. Because it is the only event which could have happened and happened. There is no event happens which is independent and unaffected and hence random. Every event is linked like chain. Like the falling objects in a queue. If you have seen cycles stand, if one is fallen, the others keep falling, suppose there are 100 cycles stand side by side, the falling of 100th cycle can be result of falling of 1st cycle. The fall of the 100th cycle is not 'random'. but is caused by the falll on 1st cycle. So what about the first one?
That first one is the event Big Bang. which is a primary event, and route cause of every other events. If i say, in first example, the accident of 'x' was destined by Big-Bang, i dont think that i am saying something awkward.
if i try to look the first event of accident from microscopic scale, a lot of event happening simultaneously, the wheel is moving, breaks, noise, and so no...!
If i try to look all event from a macroscopic point of view, every event happening at any time 't' is actually one event, when we look outside from the world. Every one of us are working as a unit.
The future events have already been decided by the very first event and nothing is random.
