Default Adding Probabilities

I apologize if this has been discussed already, but I did a search and couldn't find anything.

I am trying to figure out what the probability is that someone else has a better hand than you. I am able to figure out how likely each person is to have a better hand than you, but I am not sure how to apply that to multiple people. Can you simply multiply the probability that each person has a hand better than yours times the number of players?

For example. If there is a 10% chance that each person has a better hand than yours, and there are 5 players sitting at your table, is the probability that at least one of those players has a better hand than you 50%?

If I am correct, there is no real way to figure that out. The best you can do is figure out the win % for your current hand vs. a certain number of people.

Well it's really just a question of probabilities. Forget about Poker for a second. How do you add probabilities? When you flip a coin, you know you have a 50% chance of getting tails. If you flip two coins (or more), what is the probability that at least one of them will be tails?

I am thinking that you can just add the probabilities together, so two coins would be 100%, 3 - 150%, 4 - 200%, etc.

I am a little uneasy about this though. Something tells me I am missing something...

You are definitely missing something. I just dont know what it is.

Wait, I think I figured it out. 2 coins would be 75%, not 100%. I thought it was a little weird that it would go over 100%, because there is always a chance that you will get all heads.

I think that the formula is that for each coin you add, you add the original percent devided by the new total of coins. So 1 coin is 50%, 2 is 50% + (50% / 2), and three coins is 50% + (50% / 2) + (50% / 3). That way it will never reach 100%.

How does that sound?

Like way to much math for someone like me...
