Are some randoms more random than others?

I always wondered: If there is a 1% chance of an event happening, and you looked at 100 possible event-worlds, what are the chances of it happening once? If it is 1/100 + 1/100 ..., wouldnt that make it 100/100? Does that mean there is a 100% chance of it happening? That just sounds absurd to me. Obviously, "chances are" that it will happen, but what the heck does that mean? (Is my question clear or must I be more precise?)

eheh, probabilities... Your additive method only works with very small chances/small number of occurences, but in this case it's faulty.
A 1% chance event has an *average* chance of NOT occurring (at all) of (1-0.01)^100, that's 33.6%, so chance of occuring *at least once* is 66.4 %
However the average *number* of occurence is 1 (ie it will sometimes occur 0 time, other 1 time, or more, but average still is 1%*100 = 1)
