    I'm 31 years old and a former air traffic controller, I gave up my successful carrier to join college for the first time ever to expand my knowledge and potentials so I left home and came to the US. I was scared of math for that i never had it before in English, my native language is Arabic, plus it's been along time since I've been to class,almost 14 years.I came across one of your videos and it was just the answer to my prayers. Sir Patrick, please accept my honest gratitude and God bless you

    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.

    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.

    Thanks. Being a Math Geek or not really doesn't matter to me. It's how one communicates the theories and concepts. You make it sound simple. Thank you.

    Five items are randomly arranged. Is the probability that they'll be in any given order 1/(5!)?

    Wouldn't 29/365.25 be a more accurate probability for a birthday in February?
