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

good luck in your studies!! :)

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.

[patrickJMT]

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.

i think i will keep up with my um's and you know's. thanks though.

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!)?

[rahat karim]

nice video , can you explain how would you solve this: in a simpl experiment: chips with integers 1-20 are placed: whats the probabilty that a number drawn is a multiple of 3 and the probabilty that a number drawn is not a multiple of 4, thankyou :)

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

pls kindly help with this problems. i always struggle with words like at least 5 in probability. here is one, A fair coin is flip 14 times. find the probability that it lands on head at least 7 times? thanks

ive struggled with math all my darn life, i wish i saw your videos sooner. I sometimes feel like professors and teachers are there to make our lives more miserable than they already are :/. you are excellent. You helped me with my stats class tremendously. Thank you so much for putting oyur time in TO HELP OTHERS! awsome work please continue.
