awwww thx sooooooooooooooooooooooooooooo
oooooooooo much now i get it...i would probably donate to but college is eating my money up!!!!!!! -
@0teh0killah2 Coin flipping is a theoretical probability were as the phone number scenario is an experimental probability, just wanted to give a little info.

Romans wanted to spend less days on february when they made the calendar because it was the month of praying and they got bored and gave the days to july and august who were months named after emperors

You make it this so much easier to understand than my Professor. Thank you so much.

@kaymakliekmek (in case nobody has explained it to you yet) Think of THH and HHT as numbers, like 234 and 432. They are not both the same, they look like it but the order matters. Just like with flipping coins; flipping tails first is not the same as flipping tails last.

@patrickJMT Accordingly in your example of the "and statements" when you write down all possibilities you write H1,H2,H3 for example but not 1H,2H,3H. What is the difference of that situation with this one?
What I have a hard time grasping - and would appreciate some clarification - is if, in the second example, the probability would be greater if the three coins were flipped simultaneously? Because then HHT would equal THH, right? It seems odd to me that the act of looking, or delaying a coin toss, would somehow effect its probability. Thanks.

@0teh0killah2 not sure i quite understand. tossing the coins 'one at a time' or simultaneously makes no difference, you are correct. imagine that the coins are different colors so that we can distinguish which coins have heads and which have tails. by flipping one at a time, one would notice this distinction.
so no, HHT is not the same event as THH.

When flipping coin, does this mean that no outcome is more likely to happen than the next? Hitting all the heads is as likely as hitting HTTH for example?

@789123Y yep that is correct. any particular sequence is as likely as any other.
