I have never thought of probability like this before .... It used to look like a monster who can hardly talk some sense before I watched this playlist ... ❤️ Thanks a lot.

@greatestwhoeverlived Well, you are right in the fact that the 3 events are independant, but that is why he multiplied the probabilities (0.8 * 0.8 * 0.8) this shows that the events are independant :)

Thank you so much for posting this video!! I am in 6 th grade in 8th grade math unit, and we have been learning probability 2 hours a day for 1 week and I did not get any of it. Watching this 10 minute video I figured out everything. Thank u so much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

yes it is correct :D if you think about it you have 1000 numbers from 0 (combinations of 3 zeros) to 999 (combinations of 3 nines). the fact is that you're counting numbers with just two or one digits as combinations of zeros and the numbers (for example, the number '67' is the combination of 0+6+7). so if you want to count the real numbers of combination with 3 digits you should count the numbers from 100 to 999, so it should be 900.

@greatestwhoeverlived You're correct in saying each shot has the same chance (80%), but the odds of getting 3 shots IN A ROW is the multiplication of that percent (0.80) 3 times. Same as getting 50 tails in a row is not the same as getting one tail (50%).

although it exceeds this fine vieo, I bet that if you do it experimentally, your result for probabilities would look like a Gauss bell, where the most frequent outcomes are the most diverse combinations of H and T, such as HTH or THT, and the least frequent are the least diverse combinations of H and T, such as HHH or TTT

the highest number in probability is one, and to answer P(not getting exactly 1 head) is 1-P(getting exactly 1 head)
