If I toss 1000 coins, one at a time, the laws of probability predict about half will end up heads and the other half tails. But what does probability say if I toss all 1000 coins at the same time? I assume the probability remains the same: half will end up heads, the other half tails. So, my real question is are the laws of probability not dependent on if events are sequential or simultaneous? Assume the events are not dependent on each other in any way.
